Homework Questions

What do you remember about inequalities?

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

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

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
