Grrrr. I've seemingly breezed through the last few chapters and now for some reason I'm stuck on something that SHOULD be simple. Why can't I get this? can anyone explain this to me a simpler way than my MathLab program is? Here is the question... [/IMG] I'm on attempt 2/3 on this quiz-thing, and if I don't get an 80%, it's not going to let me move on which is a pain because then I have to wait for the teacher (who is super cool) to give me another attempt, but I need to be ready to take a test tomorrow and I've been working on this ALL day. My brain is freaking fried.
