11/12/2007 Algebra 1-Graphing Equations Review

We will be reviewing the graphing section from Chapter 4 today. As a group, the 3 classes did not perform very well on that section of the test, so we need to spend some class time reviewing. We will do some examples on the board together and then students will practice on a worksheet. We will grade it in class today when everyone is finished.

11/12/2007 Algebra 2-Solving Systems With Inverse Matrices

We continued our use of inverse matrices today. We will be using them to solve systems of equations. The process is as follows:

1) Set up matrix equation similar to above
2) Find the inverse of the square matrix
3) Multiply on the left time the column matrix

See a video demonstration here.
