Bob left his home and walked 3 miles south, 2 mile east, another 2 miles south and then 6 miles west. Can he use his walkie-talkie to call his brother Jack back at the house if the walkie-talkie has a range of 7 miles?

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

i believe that the answer is

b. y-1=-2(x-4)

hope this !
