Answer:
-3/4
Step-by-step explanation:
First, pick two coordinates.
(0,2) and (4,-1)
Then do the rise over run or y/x.
The y is 3 and the x is 4. That is 3/4.
Since the line is going down, it will be negative.
The answer is -3/4.
Answer:
The half life of the car is 3.98 years.
Step-by-step explanation:
The value of the car after t years is given by the following equation:

In which V(0) is the initial value and r is the constant decay rate, as a decimal.
The value of a certain car decreases by 16% each year.
This means that 
So



What is the 1⁄2-life of the car?
This is t for which V(t) = 0.5V(0). So







The half life of the car is 3.98 years.
i wasn't sure on how to explain it so i just attached ur answer
