Answer:
It would be (D 8)
Step-by-step explanation:
Answer:
y - x= - 13 -------(1)
- 4x + 3y = -51 -------(2)
(1) => y = - 13 + x
Substitute y in (2)
- 4x + 3( - 13 + x) = -51
- 4x - 39 + 3x = -51
- x = -51 + 39
- x = -12
x = 12
Substitute x in (1)
y = - 13 + x = -13 + 12 = - 1
x = 12, y = -1
Answer: Y=24000-3000x
9000=24000-3000x
-15000=-3000x
x=5 years
first we need to set the equation
at plug in all the information we have. In our case, we know cars value or y =9000, we need to find what is the x value
2
we need to subtract 24000 on both sides, and then divide by -3000 on both sides, and find out for x in years
