On Friday we explored vertex-edge graphs and digraphs as represented by adjacency matrices. The Okefenokee Food Web is due Monday, January 30 for extra credit. Attached is a website to help with adjacency matrices:
www.ciclt.net/ul/okresa/03%20Lesson%205_MM3A7PPT.pdf We explored matrices in real life by working on a learning task, Central High Booster Club. It is due on Friday, January 27!
We found an alternate way of solving matrix equations! It's called Cramer's Rule, and it is amazing:)
Attached are the notes and worksheet along with a helpful website. Quiz on Friday! Test on Tuesday!!! www.coolmath.com/algebra/14-determinants-cramers-rule/01-determinants-cramers-rule-2x2-01 Today we explored inverses and how to solve matrix equations using them. Please finish 1-10 of the first page. We will continue with Cramer's Rule tomorrow. Attached are some helpful websites to solve equations using the inverse:

Please complete the determinant side of the worksheet! Attached is a website for extra assistance with determinants.
www.mathsisfun.com/algebra/matrix-determinant.html Today we multiplied matrices. Test remediation is scheduled for Tuesday, January 24, 3:45-4:45 PM!
Today we learned how to add and subtract matrices, multiply by a scalar, and solve for variables in matrix equations!
Today we reviewed the slope-intercept form of a line as well as how to find different sides of special right triangles. Be sure to study up on Parts 1-4, 7, 9, and 10 for the test tomorrow!!! We will also check out our textbooks tomorrow!
Parallel and Perpendicular Lines: go to 7:35 if just want perpendicular line and point www.youtube.com/watch?v=ECljEiIgX_M Special Right Triangles: www.youtube.com/watch?v=nVTtSE5nv7c Area and Circumference of Circles: www.mathgoodies.com/lessons/vol2/circle_area.html Today we factored using a variety of methods. You are now responsible for Sections 8 and 10. Attached are the notes along with the answer key for the prerequisite packet to check your answers. Have a great weekend! Here are a couple of cross-number puzzles to practice factoring:
