Answer:

w = 9, l = 12

Step-by-step explanation:

If w is the width and l is the length, then:

l = 2w − 6

The area of the rectangle is width times length.

A = wl

Substituting and solving:

108 = w (2w − 6)

108 = 2w² − 6w

54 = w² − 3w

0 = w² − 3w − 54

0 = (w + 6) (w − 9)

w = -6 or 9

The width is 9, so the length is 12.

Slope intercept form of y=-1/7x+22/7
forsale [732]

This equation is already in slope intercept form.

Slope intercept form is y = mx + b, which is the form it is in now. However, if you would like it changed to standard form, you would multiply by the lowest common denominator and then rearrange as follows.

y = -1/7x + 22/7 -----> Multiply both sides by 7

7y = -x + 22 ------> Add x to both sides

x + 7y = 22
