Today we started reviewing for our linear systems test next Wednesday. The review handout is given below, a practice test will be given out and posted on Tuesday. I have also posted a document of all set-ups for the word problems on your review.
Today we practiced more problem solving. The scanned examples are posted below. We then had our quiz. We will be taking up page 46 #1-10 tomorrow.
Today we did two more problem solving examples. They are posted below. Practice was page 46 #1-10. They are not for homework, we will continue working on them tomorrow.
Today we spent some more time on elimination, looking at situations where we had to multiply each equation by a constant. The scanned note is posted below. Homework was p. 40 #5-7.
Today we learned about the method of elimination. The scanned note is posted below. If you weren't here, you will want to go through it, and maybe even the appropriate text section (1.4). Assigned practice was page 39 #C1, C3, 1 - 4.
Today we learned a more general method of substitution. The scanned note and solutions to the practice are scanned below. Extra practice was on page 26 #1, 2.
Today we learned about "linear systems" and what it means to solve them. The scanned note is posted below. Assigned practice was page 16 #C3, C4, 7 - 9.
