Question description

This is a algegra, precalc and tri review. I have the answers provided by the teacher. But I need to study HOW to solve these problems and it's taking forever just to figure out what to look for to study and try to solve because I don't remember. So instead of studying, i'm wasting time trying to figure out how to study. Attached is the questions and answers sheet. 

I need someone to provide step by step with explanation of how to solve 9-20 please. Details matter as I will need to study this for test. It would also be helpful if you could include the type of problem it is....for example #8 I think is solving quadratic inequalities but i don't know.

Only need help with 9-20
