Objective The student will be able to: solve inequalities using multiplication and division.

Important Step To Remember When multiplying or dividing BOTH sides by a NEGATIVE number, SWITCH the inequality!

1) Solve > 13 o k < Draw a wall 2.Clear the fraction - Multiply both sides by -4 3.NEW STEP!! When multiplying BOTH sides by a NEGATIVE number, SWITCH the inequality! 4.Simplify 5.Check your answer 6.Graph the solution

2) When solving > -10 will the inequality switch? 1.Yes! 2.No! 3.I still don’t know! Answer Now

2) Solve < -10 o x < Draw a wall 2.Clear the fraction - Multiply both sides by 3. Do you switch the inequality? No - Both sides are being multiplied by a positive number 3.Simplify 4.Check your answer 5.Graph the solution

3) When solving will the inequality switch? 1.Yes! 2.No! 3.I still don’t know! Answer Now

3) Solve o a > Draw a wall 2.Clear the fraction - Multiply both sides by -4. Do you switch the inequality? Yes - Both sides are being multiplied by a negative number 3.Simplify 4.Check your answer 5.Graph the solution

Take a quick break! Things that make you go.....Hmmm Why is abbreviation such a long word? Why is the name for fear of long words Hippopotomonstrosesquippedaliophobia?

4) Solve -8p ≥ p ≥ 12 2.p ≥ p ≤ 12 4.p ≤ -12 Answer Now

4) Solve -8p ≥ Draw a wall 2.Divide both sides by -8. Do you switch the inequality? Yes - Both sides are being divided by a negative number 3.Simplify 4.Check your answer 5.Graph the solution p ≤ 12 -8(12) = -96 ●
