AIM: Additive and Multiplicative Inverse
Solve, graph, and check the following inequality.
-4x + 16 < -12 CHECK

2. 2
Properties Jigsaw
You will receive either the additive inverse or
multiplicative inverse sheet. Read the definition, complete
the examples, and prepare an explanation. You will have to
teach this concept to another student, so take the time to
get ready.
