Warm Up September 2 Tuesday. Solve 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.

Warm Up September 2 Tuesday Solve 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
How to read it: A = { x | x ≥ 5} A is the set of all x such that x is greater than or equal to 5.
