6. Homework Questions

7. What do you remember about inequalities?

8. Solving Inequalities – Review
Solving inequalities is like solving equations with one exception
When you multiply or divide both sides by a negative you must FLIP THE SIGN
Example:3𝑥−1>−6 4+2𝑥 +10𝑥
3𝑥−1>−24−12𝑥+10𝑥
3𝑥−1>−24−2𝑥
−3𝑥+24+24−3𝑥
23>−5𝑥
− 23 5 <𝑥
𝑥>− 23 5

10. Back-to-Back Drawing
You and your partner will each get an image. DO NOT show your drawing to the other person
Partner A will be the person with the longer hair
Sit back-to-back
Partner A will describe their picture in as much detail as possible and Partner B will try to what they think the image looks like
When “time” is called, show the drawing and the image and compare then switch rolls

11. Manipulating Inequalities
Like Manipulating Equations to isolate a variable, you can manipulate two-variable inequalities
The same rule applies: When you multiply or divide both sides by a negative you must FLIP THE SIGN
Example: 4𝑥−6𝑦≥36
−6𝑦≥−4𝑥+36
𝑦≤ 2 3 𝑥−6
