Say you buy a new car in 2010 for $23,000 and depreciates linearly so that in
2015 the car is worth $5000. For this linear depreciation, find the equation (y =
mx + b). Then use that equation to find out what year the car will be worth $0. Go
out two decimal places

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

51-50

step-by-step explanation:

i believe a. 12x≥120 is the answer
