When change in one variable is accompanied by the change of another variable in the same direction, they are directly proportional to each other, and it is usually represented by the general equation, y = kx where k is a constant.
Answer:
Part A : ![w=\frac{P}{2}-l](https://tex.z-dn.net/?f=w%3D%5Cfrac%7BP%7D%7B2%7D-l)
Part B: To isolate variable
we first divided both sides by 2 to cancel out 2 on the right side. Then we subtracted
from both sides to cancel out
from the right side leaving
alone on right side.
Step-by-step explanation:
Given:
Formula for the perimeter of a rectangle :
![P=2(l+w)](https://tex.z-dn.net/?f=P%3D2%28l%2Bw%29)
To rewrite the given formula in terms of the width
.
Solution:
In order to rewrite the formula in terms of the width
, we will isolate
on one side.
We have:
![P=2(l+w)](https://tex.z-dn.net/?f=P%3D2%28l%2Bw%29)
Dividing both sides by 2.
![\frac{P}{2}=\frac{2(l+w)}{2}](https://tex.z-dn.net/?f=%5Cfrac%7BP%7D%7B2%7D%3D%5Cfrac%7B2%28l%2Bw%29%7D%7B2%7D)
![\frac{P}{2}=l+w](https://tex.z-dn.net/?f=%5Cfrac%7BP%7D%7B2%7D%3Dl%2Bw)
Subtracting both sides by
.
![\frac{P}{2}-l=l-l+w](https://tex.z-dn.net/?f=%5Cfrac%7BP%7D%7B2%7D-l%3Dl-l%2Bw)
![\frac{P}{2}-l=w](https://tex.z-dn.net/?f=%5Cfrac%7BP%7D%7B2%7D-l%3Dw)
Part A : ![w=\frac{P}{2}-l](https://tex.z-dn.net/?f=w%3D%5Cfrac%7BP%7D%7B2%7D-l)
Part B: To isolate variable
we first divided both sides by 2 to cancel out 2 on the right side. Then we subtracted
from both sides to cancel out
from the right side leaving
alone on right side.

First, you would need to graph the y intercept, which is 5.
Next, you can start graphing the slope. In order to do this, you would need to start at the y intercept or at 5, then use rise/run. Move up 2 from the y intercept and go right 3 times.
If you want to go the opposite way then you go to the left by 2 and down 3. This would still have the same value as 2/3 because -2/-3= +2/+3
