Step-by-step explanation:
Answer:
Step-by-step explanation:
Since the value of the car decreases by a common factor each year, the decay is exponential.
An exponential decay function is of the form
Therefore, the function modeling the car's decay is:
We want to determine the car's value in two years.
When t=2
The value of the car in 2 years will be A(t)=$9109.10
Answer:
x = 2
Step-by-step explanation:
Set the equations equal to each other
x + 2 = -3x + 10
+ 3x + 3x Add 3x to both sides
4x + 2 = 10
- 2 - 2 Subtract 2 from both sides
4x = 8 Divide both sides by 4
x = 2
