Weekend HW (and potential extra credit!)

Th;is weekend please complete the following (from our "Matrices and Systems of Equations Problem Set"): 

Section 8.1 (page 582): 59, 65, 71 (use rref and the augmented matrix to solve)
Section 8.3 (page 608): 47, 61, 63 (use "A inverse B" with the coefficient and solution matrix to solve)

• USE YOUR GRAPHING CALCULATOR AND MATRICES TO SOLVE (ignore the Gaussian directions). 
• This is practice for our test Tuesday!

You will  have a question like 82 or 85 in section 8.1 on  next week's test so it's a good idea to look at these! There will also be a question or two like 67/69/71 in section 8.3! If you do/try any of these with your homework and show me the work on Monday you can get an extra credit homework grade!

• (Extra Credit HW: section 8.1 #85, section 8.3 #67, 69, 71).

• If you do this extra credit you're not only getting some extra homework points, you're also doing some serious prep for our test! So do it!

Finally, if you did not turn in your graphing calculator lab, remember that it's DUE MONDAY! This should be an easy 100%!

• If you don't have a calculator but you do have an Android phone use the downloadable app on the right!
• If you don't have  calculator and you don't have an Android phone you'll have to come to finish Monday before school or during a free period/lunch on Monday!
