11/8 Algebra 2

We continued our use of inverse matrices today. We will be using them to solve sytems 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. We practiced on a worksheet in class, then students worked on the graded assignment.
