1. SEC 1: Solve and Graph Simple Inequalities
Homework: pg 30 #23-31
Learning Target: I will solve and graph one-variable inequalities and use them to solve real-world problems.
Unit 1: Linear Equations & Inequalities – The Poetry and prose of algebra
SEC 1: Solve and Graph Simple Inequalities

2. Ex 1: Quality Core Question
Solve A
x > C
x > 32 B D
x > –4

3. The Rules to Solving Inequalities
When do you flip the inequality sign?
Why does it have to be flipped?
When graphing the inequality on a number line, when will the circle be open? Closed?

4. Ex 2: Solve, graph and check.
When checking your solution you must check the boundary point (where the circle is) and another point in the shaded region.

5. Ex 3: What to do…
Graph 2 < X.

6. Ex 4: What the heck just happened?
Solve 2x – 3 > 2(x – 5)
Solve 4(x – 3) + 7 ≥ 4x + 1

7. Ex 5: Revenue
A mariachi band agrees to play at your birthday party for $200 plus 25% of the ticket sales. (Yes, you are a very popular guy/girl). How much in ticket sales will be needed for the band to receive at least $500?
