Algebraic Thursday-Help!

It's Thursday night and at my house that means it's wrestling night.  While they do that, I'm trying to figure out my son's Algebra homework.  What happened to doing Algebra without a graphing calculator.  I was good with that kind, but not this new way.  My brain hurts. I need a good cup of coffee and a book break.  I've added another book this week- The Consequences by Colette Freedman.  I'm done with the first chapter and so far, so good.  My diet is still going ok and so is the working out. I'm still craving chips. That guacamole didn't help, but at least it wasn't cheese.
