Warm Up September 2 TuesdaySolve for y. (Rewrite the equation so it says y = …)
#1 3 x + y = 15
#2 -2x + 3y = -12
Note #4 Set Builder Notation
We will discuss how to write set builder notations.
I will use both set builder and interval notations to express variables.
Set Builder Notation
• Set-
The symbol means__________________
• The symbol means ________________
Suppose we have the set A = {2, 4, 5, 8, 10, 15}• Use the correct symbol: 6 ___ A
8_____A
