if f(x) =4x -6 and g(x)=x +2

The right answer is Option C.

Step-by-step explanation:

Given inequality is

[tex]\frac{n}{7}+3\geq -4[/tex]

We will first subtract three from both sides.

[tex]\frac{n}{7}+3-3\geq -4-3\\\frac{n}{7}\geq -7[/tex]

In the next step we will multiply both sides with 7 to determine n.

Therefore,

Subtract three, then multiply by 7.

The right answer is Option C.

Answer:

Step-by-step explanation:

6x - y = 1

6x - 1 = y.....rearrange

y = 6x - 1......slope is 6. A parallel line will have the same slope.

y = mx + b

slope(m) = 6

(-5,-5)...x = -5 and y = -5

now we sub and find b, the y int

-5 = 6(-5) + b

-5 = -30 + b

-5 + 30 = b

25 = b

so ur equation is : y = 6x + 25 <==

The length of the pool is 28 meters and the width of the pool is 10.5 meters.

Step-by-step explanation:

In the scale drawing of Joe, the community pool has (length : width) = 8 : 3

Let the actual length of the pool is 8x meters and the actual width is 3x meters.

Now, given that the actual pool has a perimeter of 77 meters.

So, 2(8x + 3x) = 77

⇒ 22x = 77

⇒ x = 3.5

So, the length of the pool is 8x = 8(3.5) = 28 meters and the width of the pool is 3x = 3(3.5) = 10.5 meters. (Answer)

The length of the pool is 28 meters and the width of the pool is 10.5 meters.

The cost of each pound of jelly beans is $ 2.25 and cost of each pound of almond is $ 1.25

Solution:

Let the cost of each pound of jelly beans is "a"

Let the cost of each pound of almond is "b"

For 6 pounds of jelly beans and 2  pounds of almonds, the total cost is $16

Therefore, we frame a equation as:

6 pounds of jelly beans x cost of each pound of jelly beans + 2  pounds of almonds x cost of each pound of almond = 16

[tex]6 \times a + 2 \times b = 16[/tex]

6a + 2b = 16 --------- eqn 1

For 3 pounds of jelly beans and 5 pounds of almonds, the total cost is $13

Therefore, we frame a equation as:

3 pounds of jelly beans x cost of each pound of jelly beans + 5 pounds of almonds x cost of each pound of almond = 13

[tex]3 \times a + 5 \times b = 13[/tex]

3a + 5b = 13 ----------- eqn 2

Let us solve eqn 1 and eqn 2

Multiply eqn 2 with 2

6a + 10b = 26 --------- eqn 3

Subtract eqn 1 from eqn 3

6a + 10b = 26

6a + 2b = 16

( - ) -------------------------

8b = 10

[tex]b = \frac{10}{8} = 1.25[/tex]

Substitute b = 1.25 in eqn 1

6a + 2(1.25) = 16

6a + 2.5 = 16

6a = 13.5

Thus cost of each pound of jelly beans is $ 2.25 and cost of each pound of almond is $ 1.25

Please find the grid of Sparrows and Cardinals below.

Step-by-step explanation:

Ratio 3:1 of Sparrows to Cardinals

There are at least 7, but less than 11 sparrows that eat at Mrs. Sims bird feeder

Let's build the grid for sparrows and cardinals, this way:

Sparrows = 7 - 8 - 9 - 10 - 11

Cardinals = 2 - 3 - 3 - 3 - 4

For calculating the number of cardinals we use the ratio 3:1 and round the number of cardinals to the next whole number.

Number of sparrows 7 to 11

Number of cardinals 2 to 4

Amount =$48003.20

Step-by-step explanation:

Here apply the compound interest formula;

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

where;

P=Principal amount invested = $37500

r=rate of interest as a decimal, 2.5% =0.025

n=number of compounding per year=1

t=time period the amount in invested=10

In our case, the amount after investing will be;

[tex]A=37,500(1+0.025)^{10} \\\\A=37,500(1.025)^{10} \\\\A=48003.20[/tex]

Step-by-step explanation:

13 hours past 1:00 am is equal to 13 + 1 = 14.

Therefore the answer is 14:00 hours or we can also write this as

14:00 - 12:00  = 2 : 00 pm.

Answer:  That would be 2.00 P.M

Step-by-step explanation:

To rewrite the equation in slope-intercept form and solve for y, we isolate y on one side of the equation by subtracting 3x from both sides. The resulting equation is y = -3x + 14.

To rewrite the equation in slope-intercept form and solve for y, we need to isolate y on one side of the equation.

Given the equation 3x + y = 14, we can start by subtracting 3x from both sides to get y alone.

The equation becomes y = -3x + 14, which is now in slope-intercept form (y = mx + b) where the slope (m) is -3 and the y-intercept (b) is 14.

Answer: 3/8 can’t go to 3/2

Step-by-step explanation:

Step-by-step explanation:

First you need to make a line perpendicular to y=2/3x+5. To do that you have to know that, if we use y=ax+b, a1*a2=-1. That is if a1 and a2 are perpendicular. So we get 2/3*a2=-1. -1/ 2/3=a2. a2=-1.5. We get y=-1.5x+b. Fill in (4,0) on y=-1.5x+b abd we get 0=-1.5(4)+b. b=6

Answer:

y = (-3/2)x - 6

Step-by-step explanation:

slope of the line y= 2/3x + 5

slope = 2/3

for two perpendicular lines

slope1*slope2 = -1

so, slope2 = (-1)*(3/2) = -3/2

hence for it to pass (4,0)

slope2=(y2 - y1)/(x2 - x1)

-3/2 = (y - 0)/(x - 4)

cross multiplying

-3x -12 = 2y

the equation of the line is

y = (-3/2)x - 6

Answer:

Step-by-step explanation:

Let, the length of the first piece is x inch.

Hence, the length of the second piece is 2x.

It is given that, the length of the third piece is one inch more than four times of the first piece. Hence, the length of the third piece is 4x + 1 inch.

The total length of the steel is 22 inch.

Hence, x + 2x + 4x + 1 = 22

or, 7x = 21

or, x = 3.

The length of the second piece is [tex]2x = 2\times3 =[/tex] 6 inch.

The length of the third piece is [tex]4x + 1 = 12 + 1 =[/tex] 13 inch.

The lengths of the three pieces of steel are 3 inches, 6 inches, and 13 inches respectively.

Let's denote the length of the first piece as x. According to the problemm, the second piece is twice as long as the first piece, which could be represented as 2x. The third piece is said to be one inch more than four times the length of the first piece, which could be represented as 4x + 1. Since the total length of the steel is given as 22 inches, we write down this equation: x + 2x + 4x + 1 = 22.

Simplifying this equation, we get: 7x + 1 = 22. We then subtraact 1 from both sides to isolate the term with x on one side: 7x = 21. Finally, we solve for x by dividing both sides by 7: x = 3.

Therefore, the length of the first piece of steel is 3 inches. The length of the second piece is twice that, or 6 inches. The length of the third piece is four times the length of the first piece plus one inch, or 13 inches.

Answer: A.   2(7 – 4x) = 4(5 – 2x) – 6

C.   4(x + 4) = 2(2x + 5) + 6

Step-by-step explanation:

Infinitely solution means when all numbers are solutions . Checking the equations given one by one

A. 2(7- 4x ) = 4(5 - 2x ) - 6

Expanding , we have

14 - 8x = 20 - 8x - 6

14 - 8x = 20 - 6 - 8x

14 - 8x = 14 - 8x , this is just a typical example of infinitely many solutions because any value of x chosen will satisfy the equation.

B. 6(x - 9 ) = 6x - 54 + x

Expanding , we have

6x - 54 = 6x + x - 54

6x - 54 = 7x - 54

collecting the like terms

6x - 7x = -54 + 54

- x = 0

x = 0

This equation has just one solution at x = 0 , because 0 is the only value of x that will satisfy the equation

C. 4( x + 4 ) = 2 ( 2x + 5 ) + 6

4x + 16 = 4x + 10 + 6

4x + 16 = 4x + 16

This equation also have infinitely many solutions

D. 5 ( x - 8 ) + 10 = 5 ( x + 2 )

5x - 40 + 10 = 5x + 10

5x - 30 = 5x + 10

This equation has no solution.

Therefore , the equations with infinitely many solutions are equations A and C

Answer:

(3, 2 )

Step-by-step explanation:

Given the endpoints are (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

[ 0.5(x₁ + x₂ ), 0.5(y₁ + y₂ ) [

Here (x₁, y₁ ) = (1, 0) and (x₂, y₂ ) = (5, 4), thus

midpoint = [0.5(1 + 5), 0.5(0 + 4) ] = (0.5(6), 0.5(4)) = (3, 2 )

Answer:

(3,2)

Step-by-step explanation:

To find a midpoint of two given points, we can use the formula:

[tex](x_{m} ,y_{m} ) = (\frac{x_{1} +x_{2} }{2} , \frac { y_{1} +y_{2}}{2})[/tex]

(i.e. we just take the average of the x coordinates, and similarly, the average of the y coordinates).

so we get:

midpoint =  ( (1+5)/2, (0+4)/2 )

               =   (3, 2)

When [tex]x=0,\ f(x)=0.5,[/tex] then

[tex]0.5=a\cdot b^0\Rightarrow a=0.5\ [ b^0=1][/tex]

When [tex]x=1,\ f(x)=0.1,[/tex] then

[tex]0.1=0.5\cdot b^1\Rightarrow 0.5b=0.1,\ b=0.2[/tex]

Thus,

[tex]f(x)=0.5\cdot (0.2)^x[/tex]

Check remaining values:

[tex]f(-2)=0.5\cdot 0.02^{-2}=0.5\cdot 5^2=0.5\cdot 25=12.5\\ \\f(-1)=0.5\cdot 0.2^{-1}=0.5\cdot 5=2.5\\ \\f(2)=0.5\cdot 0.2^2=0.5\cdot 0.04=0.02[/tex]

Answer:

5 weeks

Step-by-step explanation:

There are 7 days in a week.

5 weeks * 7 days = 35 days.

Raphael ran for a total of 5 weeks.

To calculate how many weeks Raphael ran, we need to divide the number of days he ran by the number of days in a week.

Raphael ran for 35 days.

Since there are 7 days in a week, we divide 35 by 7:

35 days / 7 days per week = 5 weeks

Therefore, Raphael ran for 5 weeks.
