Determine the intercepts of the line.

Y-intercept (0,___)
X-intercept (___,0)

Answer:

1.20 + 1.40x ≥ 5, or $1.20 + $1.40x ≥ $5

Step-by-step explanation:

So since you are only buying 1 soda and you are buying multiple bags of Cheetos so you are able to use you debit card and meet the requirement of at least $5, you can make the inequality:

1.20 + 1.40x ≥ 5, or $1.20 + $1.40x ≥ $5

where x is the number of bags of Cheetos.

The average distance from the sun to Mars can be found by setting up an equation based on the given information. Subtracting 550 from the average distance to Jupiter gives the average distance to Mars, which is 228 million km.

We know that the average distance from the sun to Jupiter is 778 million km, which is 550 million km more than the distance from the sun to Mars. We could express it in the form of an equation and solve to find the average distance that Mars is from the sun. Let's denote that Mars is 'x' million km from the sun. Then we can write it as:

x + 550 = 778

To find x, we need to subtract 550 from both sides of the equation, which gives us:

x = 778 - 550

And so, the distance from the sun to Mars is x = 228 million km.

Answer:

it is the subtraction property of equality

Answer:

2160 cm³

Step-by-step explanation:

The volume of a rectangular prism is calculated using the formula

V = lbh ( l is length, b is breadth, h is height )

here l = 18, b = 10 and h = 12, hence

V = 18 × 10 × 12 = 2160 cm³

Volume = l × b × h

= 18 × 10 × 12

= 2160cm³

EXPLANATION.

The given function is

[tex]f(x) = 2 {x}^{3} + 21[/tex]

Let

[tex]y= 2 {x}^{3} + 21[/tex]

Solve for x.

[tex]2 {x}^{3} = y - 21[/tex]

[tex] {x}^{3} = \frac{1}{2} y - \frac{21}{2} [/tex]

Take cubic root of both sides,

[tex]x = \sqrt[3]{ \frac{1}{2} y - \frac{21}{2} } [/tex]

x is defined for all real values of y.

The range refers to the values of y, for which x is defined.

Hence the range is all real numbers.

In interval notation, we write this as,

The cost of each song is $1.25.

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

Given that, Amelia used a $50 gift card to buy digital music online after playing for 16 songs her balance on the gift card was $30.

So, the cost of 16 song is 50-30=$20

Now, the cost of each song = 20/16

= 5/4

= $1.25

Therefore, the price of each song is $1.25.

Answer:

Step-by-step explanation:

Theoretical probability is the probability that something should happen based on the beginning conditions.  Such as having a jar of 30 marbles with 5 being blue.  The probability of pulling out a blue marble when selecting 1 marble is

5/30, or 1/6.  Theoretically you should pull one blue marble out every 6 times you pull a marble out.  

This isn't guaranteed to happen though, that's where experimental probability comes form.

Experimental probability is the number of desired outcomes achieved, divided by the total number of outcomes.  This is based on what actually happened.  Say you selected a marble, and put it back 10 times, recording the color each time and you got 2 blue marbles.  Your experimental probability is

2/10, or 1/5, which doesn't match the theoretical probability.  The more times this experiment is conducted, the closer your result will be to the theoretical probability

22.26 x 10^7 is the correct answer

Multiply the decimal numbers:

5.3 x 4.2 = 22.26

When multiplying scientific numbers, add the exponents together: 4+3 = 7

So you now have 22.26 x 10^7

Now you need to convert 22.26 to a scientific number, by only having one number to the left of the decimal point.

You need to move the decimal 1 place to the left, which means you need to add 1 more to the exponent.

The final answer would be 2.226 x 10^8

The answer is 2. The rate of change between -1 and 0 is 3 and between 0 and -1 is 1. The average between 3 and 1 is 2.

Answer:

- 2

Step-by-step explanation:

The average rate of change in the closed interval [ a, b ] is

[tex]\frac{f(b)-f(a)}{b-a}[/tex]

here [ a, b ] = [ - 1, 1 ]

f(b) = f(1) = 1 - 2 = - 1

f(a) = f(- 1) = 1 + 2 = 3

Hence

average rate of change = [tex]\frac{-1-3}{1-(-1)}[/tex] = [tex]\frac{-4}{2}[/tex] = - 2

For this case we have that the law of cosine is given by:

[tex]c ^ 2 = a ^ 2 + b ^ 2-2 (a) (b) * cos (x)[/tex]

Where:

[tex]c = 12 \ ft\\a = 8 \ ft\\b = 9 \ ft[/tex]

We replace:

[tex]12 ^ 2 = 8 ^ 2 + 9 ^ 2-2 (8) (9) * cos (x)\\144 = 64 + 81-144 * cos (x)\\144 = 145-144 * cos (x)\\-1 = -144cos (x)\\cos (x) = \frac {1} {144}\\x = cos ^ {- 1} (\frac {1} {144})\\x = 89.60 \ degrees[/tex]

Answer:

2W=9

Step-by-step explanation:

You must first get the Length, which is 15, and multiply it by 2 and you get 30. You then subtract 30 from 48 and get 18. Since the equation has 2W, you have to divide 18 by 2, which gets you the answer 9.

Answer:

width = 9 feet

Step-by-step explanation:

Here we are given that total length of the wood for the garden is 48 feet only.

The length in represented in the equation given below. In geometry we call it Perimeter.

2l+2w=48

Where l is the length of the garden and the w is width of the garden.

Here also given that , if Manny wants the length to be 15 feet, what will be width of the garden.

In order to find this we put the value of l as 15  in 2l+2w=48 and solve for w

Let us see how

2l+2w=48

2(15)+2w=48

30+2w=48

subtracting 30 from both sides

30+2w-30=48-30

2w=18

Dividing both sides by 2 we get

w=9

Hence the width will be 9 feet

The answer would be Loan A

even though she'll pay more per month, with the others she'll pay be paying more by the time she as payed it off due to having to pay interest over a longer period of time

Answer:

Step-by-step explanation:

The different loan plans are showed in the image attached.

Loan A: 12 months of duration with 9.50%.

Loan B: 24 months of duration with 8.75%.

Loan C: 36 months of duration with 7.75%.

Loan D: 48 months of duration with 6.60%.

Now, all loans are compouneded monthly. Let's the compound interest formula

[tex]A=P(1+\frac{r}{n} )^{nt}[/tex]

Loan A:

[tex]A=2500(1+\frac{0.095}{12} )^{12(1)}\\A=2,748.12[/tex]

Loan B:

[tex]A=2500(1+\frac{0.095}{24} )^{24(2)} \\A=2500(1.004)^{48}\\ A=3,028.02[/tex]

Loan C:

[tex]A=2500(1+\frac{0.095}{36} )^{36(3)} \\A=2500(1.003)^{108}\\ A=3,454.94[/tex]

Loan D:

[tex]A=2500(1+\frac{0.095}{48} )^{48(4)}\\ A=2500(1.002)^{192}\\ A=3,668.95[/tex]

Now, if you compare, you will observe that Loan A offer the cheapest result for Judy.

Since the scuba diver jumps into the water and decreases his altitude by 5.6 meters in one minute, the equation that can be used to represent the divers altitude is [tex]y = -5x + 1.3[/tex]

The standard equation is [tex]y = mx + b[/tex]

y,x = variables

m = rate of change

b = initial value of y.

y = the height of the scuba driver after x minutes.

Given that b = 1.3

m = -5.6(decrease in altitude)

Then the equation can be written as ; [tex]y = -5x + 1.3[/tex]

hence scuba driver height is given by the equation [tex]y = -5x + 1.3[/tex]

The equation that represents the scuba diver's altitude after jumping into the water is y = 1.3 - 5.6t, where y is in meters and t is in minutes.

Let y represent the diver's altitude in meters relative to sea level after t minutes. Initially, at sea level, we have y(0) = 1.3. Due to the descent in water, the altitude decreases by 5.6 meters per minute, which means the altitude change per minute can be represented by
-5.6t. Thus, the equation that can be used to represent the diver's altitude as a function of time is:

y = 1.3 - 5.6t

where y is in meters and t is in minutes.
