Tuesday HW (same as Monday)!

Tonight, please complete questions 1a, 2a, 2b, and 3, and 5 on the "Solving Multivariable Systems!" worksheet we started in class (or below). This will be checked on Wednesday!

• For 1a solve with back substitution!
• For 3 you need to create a system that has this solution! There is not one answer to this--there are many, many answers! I would recommend making up a system that is in row echelon form--so start with z = 0 (bottom equation). Then, write an equation that incorporates y and z so that y = 1 (middle equation). Finally, write a (top) equation that incorporates x, y, and z so that x = 2 (given that y = 1 and z = 0).
• It is also possible to answer this with a system that is not in row echelon form.
• If you write two answers to question c--one system with the solution (2,1,0) in row echelon form, and another system with this solution that has an x,y, and z term for each equation--you will receive homework extra credit! You will have to turn this in to me tomorrow!
• For 5, even though it looks complex (because it's an application problem), your challenge is to solve that given system using your row operations! Good luck!
• If you were out today we worked on questions 2a and 2b in class--do those and you're all caught up!

Here are the answers so you can check yours:

1.) (-2, -3.3333, -4)

2a.) (-2, -3, 3)

2b.) (-5, -5, 3)

3.) Answer will vary (we'll discuss tomorrow)

5.) (1, 2, 1)

See you all tomorrow for some new stuff!
