Intermediate algebra problem help?
I have been working on some homework questions for my college intermediate algebra class and am having troubles with some of the problems. Anyone who can help, I would be greatly appreciative! These homework problems are for our own sake, and are not to turn in so I am not asking you to do my homework, I am asking you to help me so I can understand a little better before our next quiz. Thanks ahead of time!
