Know anything about absolute value inequalities?
I'm trying to study all the math I forgot so I don't do too dismally bad on the Math Placement Exam for UMD.
So I hit the third-- wait, no, fourth-- question on the review sheet I got from a teacher and I'm stuck.
If you remember anything, help would be greatly appreciated.

And I also have the answers, I just don't know how/why to get to them. So the answer:
I actually managed to get the right numbers, just not in the right format.
EDIT: Damn, now I feel dumb. As it turns out, my library pays for a 24-hour tutoring service. They explained and it all came flying back.
