Objective The student will be able to:

1
ObjectiveThe student will be able to
solve inequalities using multiplication and
division.
2
1) Which graph represents the correct answer to
gt 1

?
3
1) Solve gt 13

1. Clear the fraction - Multiply both sides by -4
2. NEW STEP!! When multiplying BOTH sides by a
   NEGATIVE number, SWITCH the inequality!
3. Simplify
4. Check your answer
5. Graph the solution

k lt -52
4
2) When solving gt -10will the inequality
switch?

1. Yes!
2. No!
3. I still dont know!

5
2) Solve lt -10

• 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 lt -30

3) When solving will the inequality switch?

1. Yes!
2. No!
3. I still dont know!

3) Solve

• 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 gt -24

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-thrus?

4) Solve -8p -96

1. p 12
2. p -12
3. p 12
4. p -12

10
4) Solve -8p -96

• 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
