Answer:
(f•g)(3) = -7
Step-by-step explanation:
f(x)=-2x + 7
g(x) = x^2 – 2
(f•g)(3) = -2(x² - 2) + 7
(f•g)(3) = -2x² + 4 +7
(f•g)(3) = -2x² + 11
(f•g)(3) = -2(3)² + 11
(f•g)(3) = -2(9) + 11
(f•g)(3) = -18 + 11
(f•g)(3) = -7

Given:
where, 
.
To find:
The value of 
.
Solution:
We have,
Differentiate with respect to x.
Using chain rule, we get
Now, put x=5.
![[\because g(5)=-1,g'(5)=8]](https://tex.z-dn.net/?f=%5B%5Cbecause%20g%285%29%3D-1%2Cg%27%285%29%3D8%5D)
![[\because f'(-1)=3]](https://tex.z-dn.net/?f=%5B%5Cbecause%20f%27%28-1%29%3D3%5D)
Therefore, the value of is 24.
Knowing that a year later, the car is only worth 0.80 x, you can simplify that by stating that one year after purchase, the car is only worth 80% of its original purchase price.
Another way of stating that is that the car lost 20% of its value of the course of one year.
Answer:
the answer is A. x + y = 29, 5x + 2y = 100
