Answer:
He is 20 at oldest, or ![x\leq 20](https://tex.z-dn.net/?f=x%5Cleq%2020)
Step-by-step explanation:
The first step in finding a possible age is:
Subtract 10 from 51, and you get 41. Divide by 2, and you get about 20.5.
This means Joe is younger than or 20 years old.
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)
.
