Hi guys (and gals)...

Remember, the review worksheets that were attached to your quiz on Thursday are due on MONDAY!! I just did two of the problems from the "Graphing Systems of Inequalities" one that I thought it might help to see. (I talked through them, too, but then realized that my computer doesn't have a mic. Oh well.) If you're having trouble graphing lines, absolute values, or inequalities, please check it out! (Then keep scrolling down - there's even more!)

I'm sure you'll all be happy to know that I fixed the mic problem. So here's some help on how to set up the systems for the last two problems on WS 3.4 (#2). If you're having trouble, watch, listen, and then try it on your own!

Here are the notes from today:




Systems of inequalities for your homework problems:
#23. x = yellow cake, y = strawberry cake
because we can't have negative cakes, x >= 0, y >= 0
2 hours for yellow and 3 hours for strawberry: 2x + 3y <= 450
Revenue: 25x + 35y

#25. x = play houses, y = sheds
we can't have negative houses/sheds, so x >= 0 and y >= 0
2.5x + 2y <= 20
x + y <= 45

Here are the answers for your review worksheet... check 'em!

Just because maybe some of you need some help with this:
