Answer:
-1.9
Step-by-step explanation:
I rounded it to the tenth
We need to know the definition of the "combined function" h(x). I'm going to guess--by looking at answers--that the function is
![h(x)=\frac{f(x)}{g(x)}](https://tex.z-dn.net/?f=h%28x%29%3D%5Cfrac%7Bf%28x%29%7D%7Bg%28x%29%7D)
making it
![h(x)=\frac{5x+1}{x^2-9}](https://tex.z-dn.net/?f=h%28x%29%3D%5Cfrac%7B5x%2B1%7D%7Bx%5E2-9%7D)
This function is undefined wherever the denominator is equal to 0 (division by zero is undefined). Factor the denominator.
![h(x)=\frac{5x+1}{(x+3)(x-3)}](https://tex.z-dn.net/?f=h%28x%29%3D%5Cfrac%7B5x%2B1%7D%7B%28x%2B3%29%28x-3%29%7D)
The two values of x that make the denominator 0 are 3 and -3, otherwise written
![x=\pm 3](https://tex.z-dn.net/?f=x%3D%5Cpm%203)
.
The math I used is probably not the quickest way, but for me, the easiest.
25*5=125 25+20=45 45*7=315 125+315=440 25*4=100 440+100=540 5+7+4=16
B is your answer.

2x-x-5
For question between 13 -> 17 replace n with the number.
Example:
13.) n = 2; 2+(-1) = 1
