A Line Has Slope 2/3 And Yintercept 2.Which Answer Is The Equation Of The Line?(picture Is My Choices)

Answers

Answer 1
The general form of a straight line equation is given by

y = mx + c

Where 'm' is the gradient and 'c' is the y-intercept

We have:
m = ²/₃
c = -2

Plug in the value of 'm' and 'c', we have:

y = ²/₃x - 2

Answer: Second option


Answer 2

The generic form of straight line consisting of slope and y intercept  is given by

y = mx + c

Where 'm' is the slope of the straight line  and 'c' is the y-intercept

In the problem, it is given that slope of the line is 2/3 and y intercept is -2 :

m = ²/₃

c = -2

By putting these values in the equation above, we get:

y = ²/₃x - 2

Hence, the second option is correct.  

Hope it helps ..!!

Thank you :)

A farmer is enclosing a rectangular area for a pigpen. He wants the length of the pen to be 20 ft longer than the width. The farmer can use no more than 100 ft of fencing. What is the pen’s greatest possible length?

Let w represent the width of the pen. What expression represents the length?

Enter your response in the box.

Answers

2l+2w=100
2(w+20)+2w=100
2w+40+2w=100
4w+40=100
4w=60
w=15
l=w+20
l=15+20
Greatest length is 35ft.

Answer:

a) The greatest possible length is 35.

b) l = w + 20

Step-by-step explanation:

The farmer wants the length of the pen to be 20ft longer than the width. If we use w to represent the width. Then the length would be w + 20

The problem first ask us to find the greatest possible length considering the fencing will be no more than 100ft.

We know that the perimeter of a rectangular area is: 2l + 2w (where l is the length and w the width)

Therefore for the fencing we would need 2l + 2w ≤ 100.

We are going to substitute the values for l and w that we mentioned at the beginning and solve for w:

2l + 2w ≤ 100

2(w+20) +2w ≤ 100

2w + 40 +2w ≤ 100

4w ≤ 100 - 40

4w ≤60

w ≤ 15

Therefore the width has to be less or equal to 15.

Since the length is 20 ft longer than the width, the greatest possible length happens when the width has its greatest value.

So when w = 15, the length is 35 and this is the greatest possible length of it.

b) The expression that represents the length (as we said before) is w + 20

1. Write an expression for the slope of line r
2. Write an expression for the slope of line s
3. Line q is a vertical translation of line s 3 units down. P'' is the image of P'. What are the coordinates of P''?

Answers

1. slope = (n-k)/(m-j) 2. slope = (n-k))/(m-j) 3. P" = (m,n+e-3) 1. The slope of a line is the ratio between the change in y in regard to the change in x. Since we have two known points on the line r, we can simply subtract their respective x and y coordinates and divide. So slope = (n-k)/(m-j) One thing to pay attention to is to do the subtraction IN THE SAME ORDER. The actual order doesn't matter as long as it's the same for both top and bottom. For instance, this is another equation for the slope that's just as valid. slope = (k-n)/(j-m) 2. This is the exact same way. Just subtract the different y coordinates and divide by the difference between the x coordinates. slope=((n+e)-(k+e))/(m-j) Now because of the associative property, we can do some rearrangement of the expression to get slope=(n+e-k-e))/(m-j) and the "e" terms cancel each other, giving slope=(n-k))/(m-j) And you'll see that the slope is the same as for problem #1 above. 3. For this, let's look at the coordinates of point P' P' = (m,n+e) Since we want to move it 3 units down, just subtract 3 from the y coordinate, so P" = (m,n+e-3)

Write the point-slope form of the given line that passes through the points (0, 3) and (4, 0). Identify (x1, y1) as the x-intercept of the line. Include your work in your final answer. Type your answer in the box provided or use the upload option to submit your solution.

Answers

The point slope form of the line has the following form:

y – y1 = m (x – x1)

 

The slope m can be calculated using the formula:

m = (y2 – y1) / (x2 – x1)

m = (3 - 0) / (0 – 4) = - ¾

 

So the whole equation is:

y – 0 = - ¾ (x – 4)

y = - ¾ (x – 4) or

y = - 0.75 (x – 4)

there are 36 people in a fitness studio.3/8 of the people lifted weights. 1/3 of the people did cross training. the remaining people were running. what fraction represents the number of people running

Answers

Answer:

→Number of people in the fitness club= 36 People

→Number of people who lifted weights [tex]=\frac{3}{8}\times 36=\frac{108}{8}[/tex]

→Number of people who did cross training [tex]=\frac{1}{3}\times 36=12[/tex]

=12 People

Number of people who were running

 [tex]=1-\frac{3}{8}-\frac{1}{3}\\\\=\frac{24-9-8}{24}\\\\=\frac{7}{24}[/tex]

To determine the fraction of people running in the fitness studio, subtract the fractions of people lifting weights and doing cross training from the total, which comes to 7/24.

The fraction representing the number of people running can be found by adding the fractions of people lifting weights and doing cross training and subtracting that from the total, which gives the fraction of people running. Here's how:

Given: 3/8 lifting weights, 1/3 doing cross training, and the total is 1 (representing the whole).To find the fraction running: 1 - (3/8 + 1/3) = 1 - (9/24 + 8/24) = 1 - 17/24 = 7/24.

find the probability that a randomly selected automobile tire has a tread life between 42000 and 46000 miles

Answers

Given that in a national highway Traffic Safety Administration (NHTSA) report, data provided to the NHTSA by Goodyear stated that the mean tread life of a properly inflated automobile tires is 45,000 miles. Suppose that the current distribution of tread life of properly inflated automobile tires is normally distributed with mean of 45,000 miles and a standard deviation of 2360 miles.

Part A:

Find the probability that randomly selected automobile tire has a tread life between 42,000 and 46,000 miles.
The probability that a normally distributed data set with a mean, μ, and standard deviation, σ, is between two numbers, a and b is given by:
[tex]P(a \ \textless \ X \ \textless \ b) = P(X \ \textless \ b) - P(X \ \textless \ a) \\ \\ P\left(z\ \textless \ \frac{b-\mu}{\sigma} \right)-P\left(z\ \textless \ \frac{a-\mu}{\sigma} \right)[/tex]
Given that the the mean tread life of a properly inflated automobile tires is 45,000 miles a standard deviation of 2360 miles.
The probability that randomly selected automobile tire has a tread life between 42,000 and 46,000 miles is given by:
[tex]P(42,000 \ \textless \ X \ \textless \ 46,000) = P(X \ \textless \ 46,000) - P(X \ \textless \ 42,000) \\ \\ P\left(z\ \textless \ \frac{46,000-45,000}{2,360} \right)-P\left(z\ \textless \ \frac{42,000-45,000}{2,360} \right) \\ \\ =P(0.4237)-P(-1.271)=0.66412-0.10183=\bold{0.5623}[/tex]


b. Find the probability that randomly selected automobile tire has a tread life of more than 50,000 miles.
The probability that a normally distributed data set with a mean, μ, and standard deviation, σ, is greater than a numbers, a, is given by:
[tex]P(X \ \textgreater \ a) = 1-P(X \ \textless \ a) \\ \\ =1-P\left(z\ \textless \ \frac{a-\mu}{\sigma} \right)[/tex]
Given that the the mean tread life of a properly inflated automobile tires is 45,000 miles a standard deviation of 2360 miles.
The probability that randomly selected automobile tire has a tread life of more than 50,000 miles is given by:
[tex]P(X \ \textgreater \ 50,000) = 1 - P(X \ \textless \ 50,000) \\ \\ =1-P\left(z\ \textless \ \frac{50,000-45,000}{2,360} \right)=1-P(z\ \textless \ 2.1186) \\ \\ =1-0.98294=\bold{0.0171}[/tex]


Part C:

Find the probability that randomly selected automobile tire has a tread life of less than 38,000 miles.
The probability that a normally distributed data set with a mean, μ, and standard deviation, σ, is less than a numbers, a, is given by:
[tex]P(X \ \textless \ a) =P\left(z\ \textless \ \frac{a-\mu}{\sigma} \right)[/tex]
Given that the the mean tread life of a properly inflated automobile tires is 45,000 miles a standard deviation of 2360 miles.
The probability that randomly selected automobile tire has a tread life of less than 38,000 miles is given by:
[tex]P(X \ \textless \ 38,000) = P\left(z\ \textless \ \frac{38,000-45,000}{2,360} \right) \\ \\ =P(z\ \textless \ -2.966)=\bold{0.0015}[/tex]


d. Suppose that 6% of all automobile tires with the longest tread life have tread life of at least x miles. Find the value of x.
The probability that a normally distributed data set with a mean, μ, and standard deviation, σ, is greater than a numbers, x, is given by:
[tex]P(X \ \textgreater \ x) = 1-P(X \ \textless \ a) \\ \\ =1-P\left(z\ \textless \ \frac{a-\mu}{\sigma} \right)[/tex]
Given that the the mean tread life of a properly inflated automobile tires is 45,000 miles and a standard deviation of 2360 miles and that the probability that all automobile tires with the longest tread life have tread life of at least x miles is 6%.

Thus:
[tex]P(X \ \textgreater \ x) =0.06 \\ \\ \Rightarrow1 - P(X \ \textless \ x)=0.06 \\ \\ \Rightarrow P\left(z\ \textless \ \frac{x-45,000}{2,360} \right)=1-0.06=0.94 \\ \\ \Rightarrow P\left(z\ \textless \ \frac{x-45,000}{2,360} \right)=P(z\ \textless \ 1.555) \\ \\ \Rightarrow \frac{x-45,000}{2,360}=1.555 \\ \\ \Rightarrow x-45,000=2,360(1.555)=3,669.8 \\ \\ \Rightarrow x=3,669.8+45,000=48,669.8[/tex]
Therefore, the value of x is 48,669.8


e. Suppose that 2% of all automobile tires with the shortest tread life have tread life of at most x miles. Find the value of x.
The probability that a normally distributed data set with a mean, μ, and standard deviation, σ, is less than a numbers, x, is given by:
[tex]P(X \ \textless \ x) =P\left(z\ \textless \ \frac{a-\mu}{\sigma} \right)[/tex]
Given that the the mean tread life of a properly inflated automobile tires is 45,000 miles and a standard deviation of 2360 miles and that the probability that all automobile tires with the longest tread life have tread life of at most x miles is 2%.

Thus:
[tex]P(X \ \textless \ x)=0.02 \\ \\ \Rightarrow P\left(z\ \textless \ \frac{x-45,000}{2,360} \right)=1-0.02=0.98 \\ \\ \Rightarrow P\left(z\ \textless \ \frac{x-45,000}{2,360} \right)=P(z\ \textless \ 2.054) \\ \\ \Rightarrow \frac{x-45,000}{-2,360}=2.054 \\ \\ \Rightarrow x-45,000=-2,360(2.054)=-4,847.44 \\ \\ \Rightarrow x=-4,847.44+45,000=40,152.56[/tex]
Therefore, the value of x is 40,152.56

You are considering buying one of two brands of barbecue grills. Brand F costs $650 and will last for about fifteen years. Brand G costs $200 and will last for about five years, so you will need to buy three of them over the years to equal one Brand F grill. In either case, you plan to pay for the grill with your credit card, which has an interest rate of 13.01%, compounded monthly. You will pay off a Brand F grill in five years of monthly payments, and you will pay off a Brand G grill in three years of monthly payments. Assuming that you have no other purchases on your credit card, over a fifteen-year period, which kind of grill will be cheaper, and how much cheaper will it be? (Round all dollar values to the nearest cent.) a. Brand G will end up costing $159.48 less than Brand F. b. Brand G will end up costing $50.00 less than Brand F. c. Brand F will end up costing $134.28 less than Brand G. d. Brand F will end up costing $91.08 less than Brand G.

Answers

a. Brand G will end up costing $159.48 less than Brand F.

Answer:

a. Brand G will end up costing $159.48 less than Brand F.

Step-by-step explanation:

If you calculate the compound interest of paying the $650 barbecue to five years the cos would be around 1050 after paying the compound interests of 13.01% monthly, and when you calculate the cost of paying off a $200 over 3 years the cost of the three would be $898, so it would be cheaper to buy the three $200 barbecues over the spam of 15 years, that would be the answer.

which facility is cheaper?

Answers

Okay. We know that Center A charges $395 for an entire year. For Center B, there is a $25 sign up fee to pay one time, and then there is $15 monthly fee and $5 per aerobics class. There are 12 months in 1 year and 15 * 12 = 180. There are 52 weeks in 1 year, so 5 * 52 is 260. 260 + 180 + 25 = 465. He would pay $465 a year at Center B. Based off of the numbers, if Billy were to use a facility for only a year and go to aerobics once a week, then Center A is definitely cheaper than Center B. 

The Least expensive club for Billy to use for a year would be; Center B

What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Let just compare the cost of both the centers.

Cost of Center A:

One time charge of $495 in one complete year.

Cost of Center B:

Flat $25 dollar sign up fee

$15 per month, thus 15 x 12 = 180 dollars a year

$5 per aerobic class, so   5 x 52 = 260. dollars a year (given that Billy goes to class once a week)

There are 52 weeks in a year.

260 + 180 + 25 = 465  dollars

Hence, Center B would cost 30 dollars cheaper.

The Least expensive club for Billy to use for a year would be; Center B

Shailen is adding three numbers he gets a sum that is an even number between 10 and 20 show two addition equation shailen could have written

Answers

Let these there numbers be assigned to variables x, y and z. Since you want to find the sum, add all numbers. However, the sum has boundaries between 10 and 20. Therefore, you will have to use inequality symbols. The two addition equations that could be formulated are:

x+y+z > 10
x+y+z < 20

In both cases, the sums fall between 10 and 20 and are even. It's worth noting commutativity of addition, which says the order in which numbers are added doesn't change the sum. Hence, you can rearrange the numbers in the addition (e.g., 3 + 4 + 8 or 8 + 4 + 3) and the sum will still remain the same.

Giuliana has 22 quarters and dollar coins worth a total of $10.75.

Which equation can be used to find d, the number of dollar coins Giuliana has?

d – 22 + 0.25d = 10.75
0.25d + 22 – d = 10.75
0.25(22 – d) + d = 10.75
d + 0.25(d – 22) = 10.75

Answers

Let

q------> the number of quarters coins

d------> the number of dollars coins

we know that

[tex]1\ quarter=\$0.25[/tex]

[tex]q+d=22[/tex]

[tex]q=22-d[/tex] ------> equation A

[tex]0.25q+d=10.75[/tex] -----> equation B

substitute equation A in equation B

[tex]0.25[22-d]+d=10.75[/tex]

therefore

the answer is the option

[tex]0.25[22-d]+d=10.75[/tex]

What is an equation?

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given that Giuliana has 22, quarters and dollar coins worth a total of $10.75.

Let the number of dollar coins be represented by d, while the number of quarter coins be represented by (22-d). Therefore, the sum of the total amount that is with Giuliana can be written as,

(1 x d) + (0.25 x (22-d)) = 10.75

d + 0.25(22-d) = 10.75

Hence, the equation can be used to find d, the number of dollar coins Giuliana has is 0.25d + 22 – d = 10.75.

you want to mail a gift that is in the shape of a rectangular prism with the dimensions 25 cm by 32 CM by 40 cm .what is the minimum amount of brown paper you need to cover the gift? helppp

Answers

check the picture below.

notice, the gift box is just 6 rectangles stacked up to each other at the edges,

left and right, two rectangles of 32x40

top and bottom, two rectangles of 25x32

front and back, two rectangles of 25x40

so, just get the area of all 6 rectangles, add them up, and that's the "surface area" of the rectangular prism, and that's how much paper will be needed to cover it.

plz help due tomorrow.

Answers

So your equation will be:

2(x+6) + 2(x+2) = 2(x+4) + 2(2x-2)

First, divide everything by 2

x+6+x+2 = x+4+2x-2

Then, combine like terms

2x+8 = 3x+2

Move the variables (the x's) to one side and the numbers to the other by subtracting 2x from one side and then 2 from the other

6 = 1x or 6 = x

Now that you know that x = 6, you go back to Earl's length and width equations

Length = x+2
Width = x+6

And plug in the value of x you got (6)

Length = 6+2 = 8
Width = 6+6 = 12

There are you answers! Hope this helped! (remember to add units, in this case the units are feet)
