Week 7

As of Thursday of week 6 both classes have transitioned to new topics. I'll post answers to the exams as soon as I have created an answer file for them. Please put your emotions behind you and try to embrace the next set of topics with renewed fervor.

A special shout-out to the high performers from the junior class. Here are the top four scorers.

Algebra II is going to spend three weeks on linear equations beginning with 7 days of pure skills review followed by 7 days of applying linear equations. It is crucial that we focus on mastering the basic skills relating to lines, because they will serve as a basis or at least reference point for all that follows. Please find video links, our class notes (for the first seven days), and the homework below.

Precalculus will also be turning to linear equations, but in the context of systems. We will review the basic mechanics around solving systems of equations both algebraically and graphically, but will quickly move onto matrices.
