Please help I've been staring at this question for awhile

step-by-step explanation:

i think you should think about the question and not look online.

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

47 - 90 = 43

43 - 180 = x

x = 137

slope is 35 and 20 miles is the y-intercept.
