Answer:

1. 14 inches and 21 inches

2.

\frac{1}{7}

Step-by-step explanation:

1.Since the rectangle has been increased by a factor of 7. Therefore

2 \times 7 = 14 \\ 3 \times 7 = 21

2. As you have increased it by a factor of 7. To reduce it, multiply by a factor of

Help me find the range of this function please
lara31 [8.8K]

Answer:

{-2, -14, -26, -50}

Step-by-step explanation:

The range of the function is the function evaluated at each point of the given domain. So to find the range of the function we need to find the value of the function for each point in the domain:

- For x = -8

f(x)=-2x-18

f(-8)=-2(-8)-18

f(-8)=16-18

f(-8)=-2

The first value of the range of the function is -2

- For x = -2

f(x)=-2x-18

f(-2)=-2(-2)-18

f(-2)=4-18

f(-2)=-14

The second value of the range is -14

- For x = 4

f(x)=-2x-18

f(4)=-2(4)-18

f(4)=-8-18

f(4)=-26

Th third values of the range is -26

- For x = 16

f(x)=-2x-18

f(16)=-2(16)-18

f(16)=-32-18

f(16)=-50

The fourth and last value of the range is -50

Now we can put all the values of the range together

The range of the function is {-2, -14, -26, -50}

Solve the equation. Graph the solution(s) if possible.<br><br> ∣x−3∣+4=9
Mazyrski [523]

Answer:

x=8

x=-2

Step-by-step explanation:

∣x−3∣+4=9

= ∣x−3∣=5

<u>Positive term: (x-3)</u>

  (x-3) = 5

Rearrange and Add up

  x = 8

<u>Negative term: -(x-3)</u>

Multiply

     -x+3 = 5  

Rearrange and Add up

     -x = 2  

Multiply both sides by (-1)

     x = -2

Gabriel wants to solve the equation 5/8 m=25. What step should he do to get m by itself on one side of the equation?
Alex Ar [27]
He should first multiply both sides by 8, to get rid of the denominator.

5/8 m = 25
8(5/8 m) = 8(25)
5m = 200

He should then divide both sides by 5, to get rid of the coefficient

5m/5 = 200/5
m = 40

So m = 40 by these steps
