At least I got 30 (a) right.

Note 1: Occasionally, I like to search through my textbooks for interesting questions. I found quite a few problems for which I would like to see your work from start to finish. Look in the Algebra forum.

Note: After tonight, we will take a small break from precalculus for a few days. I need to give you some breathing room. I also need a mental break from mathematics.
