ANSWER
After 7 years the car will worth, 7,759.5
EXPLANATION
The initial value of the car is 37000.
The rate of depreciation is 20%
In 7 years time, we can calculate the value of the car using the formula,

We substitute the values into the formula to obtain,



to the nearest tenth
Answer: 0.457
multiply 3 by 7, and get 21
multiply 1 by 5, and get 5.
5 × 7 = 35.
fraction: 21/35 and 5/35
Subtract the numerators
21 − 5 = 16 = 16/35
Now we need to simplify the fraction that we have.
17 is larger than 16. So we're done reducing numbers.

1) Point-slope form
(y-y1)=m(x-x1)
m= - 3,
point (3,-4), so x1 = 3, y1 = - 4.
(y+4)= -3(x- 3)
2)Point-slope form
(y-y1)=m(x-x1)
m= - 3/4,
point (4,5), so x1 = 4, y1 = 5.
(y-5)= - 3/4(x-4)
-2 < -3 (I think so anyway)
