1. Evaluate the expressions if: x = 2 y = -9 z = 3
Warm-Up:
Evaluate the expressions if: x = y = z = 3
xy xz y -z xz

2. Now work together to find the solution for each expression if, b = 3
Think-Pair-Share
Talk with your side partner to determine what the difference is between: -7b and (-7b)2
Now work together to find the solution for each expression if, b = 3

There is a crime that needs to be solved!
Last Halloween, something was stolen from one of
the teachers. It is YOUR job to figure out from
WHOM the item was stolen, and WHO did the stealing, in order to make sure it doesn’t happen again THIS Halloween!
Your prime suspects are:
