Objective The student will be able to: solve inequalities using multiplication and division. Designed by Skip Tyler, Varina High School

1) Which graph represents the correct answer to > 1 -4 -3 -5 o -4 -3 -5 ● -4 -3 -5 ● -4 -3 -5 Answer Now

1) Solve > 13 k < -52 o -52 -51 -53 Draw “the river” Clear the fraction - Multiply both sides by -4 NEW STEP!! When multiplying BOTH sides by a NEGATIVE number, SWITCH the inequality! Simplify Check your answer Graph the solution k < -52 o -52 -51 -53

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

2) Solve < -10 x < -30 o -30 -29 -31 Draw “the river” Clear the fraction - Multiply both sides by 3. Do you switch the inequality? No - Both sides are being multiplied by a positive number Simplify Check your answer Graph the solution x < -30 o -30 -29 -31

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

3) Solve a > -24 o -24 -23 -25 Draw “the river” Clear the fraction - Multiply both sides by -4. Do you switch the inequality? Yes - Both sides are being multiplied by a negative number Simplify Check your answer Graph the solution a > -24 o -24 -23 -25

Things that make you go.....Hmmm Take a quick break! Things that make you go.....Hmmm Why is abbreviation such a long word? Why do they have braille dots on the ATM machines in drive-thru’s?

4) Solve -8p ≥ -96 p ≥ 12 p ≥ -12 p ≤ 12 p ≤ -12 Answer Now

4) Solve -8p ≥ -96 p ≤ 12 -8(12) = -96 ● 12 13 11 Draw “the river” Divide both sides by -8. Do you switch the inequality? Yes - Both sides are being divided by a negative number Simplify Check your answer Graph the solution p ≤ 12 -8(12) = -96 ● 12 13 11

● ● 5) Solve 7v < -105 o o -15 -14 -16 -15 -14 -16 -15 -14 -16 -15 Answer Now
