Section 4.3:
We have already done these problems using one equation with
one variable (x). pg. 241 For the problems on this page, set up the even
ones using two equations with two unknowns, an x and a y.
Pg. 242 & 243
&244 We have done problems on this page using one unknown and one
equation. Here we are to set up the problem using both an x and a y.
Do
the even problems on these pages, using two unknowns, but you may skip
the concept check. Pg 246 – solve #48 using three equations with three
unknowns.
Section 4.4 - I will bring in using the methods of Section 4.4 as we do the
problems in sections 4.2 and 4.3 We will not cover this section in particular,
but you may do any even problems as you wish for extra credit.

Chapter 6
The first four sections of chapter 6 are on factoring. If you are not familiar with factoring, you should
probably watch some videos from the first four sections. I have created a homework assignment on
factoring that I expect you to do on your own. This is material that is taught in intermediate algebra,
but it is easy to forget. As a class we are going to jump into section 6.5 and then have a quiz on that
section only. It is important that you do this homework assignment on Chapter six, sections 1 to 4.
You may do the following, and these only, for extra credit in sections 1 to 4:
Section 1 pg. 324 # 8, 14, 18, 20, 26, 42, 46, 50, 56,
Section 2, pg. 332 # 6, 14, 18, 22, 28, 34, 44, 56, 60,
Section 3, pg. 337 # 10, 14, 20, 22, 50, 56
Section 4, pg. 342 # 10, 12, 16, 18, 22, 28, 30, 32, 42, 65
