Guided Notes
Key concepts students will learn:
- •
When solving inequalities, treat the greater than or less than sign the same way you would treat an equal sign.
- •
If you multiply or divide both sides of an inequality by a negative number, you must swap the inequality sign.
- •
When solving the inequality -13x > -5, you must divide both sides by -13, which means the solution is x < 5/13.
