Answer Now

1) Which graph represents the correct answer to > 1

1 solve 13
o

-53

-52

-51

1) Solve > 13
  • 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

2 solve 10
o

-31

-30

-29

  • 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

2) Solve < -10

x < -30

3 solve
o

-25

-24

-23

3) Solve
  • 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

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
Answer Now4) Solve -8p ≥ -96
  • p ≥ 12
  • p ≥ -12
  • p ≤ 12
  • p ≤ -12
4 solve 8p 961

12

13

4) Solve -8p ≥ -96
  • 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

5 solve 7v 105
