Suppose that $f(-5)=-5,$ $g(-5)=2,$ $f'(-5)=3,$ and $g'(-5)=8.$ Find $h'(-5)$ for the following.

---

1. $h(x) = 5 f(x) - 4 g(x)$
Answer: $h'(-5) =$

2. $h(x) = f(x) g(x)$
Answer: $h'(-5) =$

3. $\displaystyle h(x) = \frac{f(x)}{g(x)}$
Answer: $h'(-5) =$

4. $\displaystyle h(x) = \frac{g(x)}{1+f(x)}$
Answer: $h'(-5) =$
