Solving inequalities

What inequality does the number line graph represent?

• x > 5

• x < −5

• x ≥ 5

• x ≥ −5

Pick the correct letter for:
6 > x

• A

• B

• C

• D

-4x + 14 ≤ 54

• x ≥ - 10

• x ≤ -10

• x ≥ 10

• x ≤ 10

5z - 2 - 2z < 13

• z > 5

• z < 5

• z > 1

• z < 1

Does the sign need to flip when solving?
8y < (-40)

• YES

• NO

Do you flip the sign?
-3x + 2  ≤  22

• YES

• NO

If 15 > x - 1  then a possible set of solutions for x is...

• 1, 7, 15

• 19, 22, 30

• 80, 100  

Solve:
3(x - 2) < 2(x + 9)

• x<24

• x>12

• x<12

• x>24

Solve:
7(x + 3) < 5x + 13

• x>-4

• x < 17

• x<-4

• x > -17

You flip an inequality symbol when you...

• subtract

• multiply and divide only

• multiple by a negative number

• multiple or divide by a negative number
