Inequalities Unit Review

When graphing an inequality, you use an open dot when you use which symbol?

• <, >

• ≤, ≥ 

Match the graph with its inequality.

• 11 < a

• 11 > a

•  11 ≤ a

•  11 ≥ a

Write an inequality for this situation:
You are driving, and the maximum speed limit is 55.

• s < 55

• s > 55

• s ≤ 55

• s ≥ 55

Solve the inequality.
x + 5 ≤ 13

• x ≥ 8

• x ≥ 18

• x ≤ 8 

• x ≤ 18 

Do I need to flip my sign?

3x ≥ -12

• Yes

• No

6 - 2h > 30

• h < 24

• 18 > h

• h > 12

• h < -12

4x - 2 ≤ -22

• x ≥ -5

• x ≥ -6

• x ≤ -6

• x ≤ -5

5z - 2 - 2z < 13

• z > 5

• z < 5

• z > 1

• z < 1

-2(x+2) < 14

• x < - 5

• x > -5

• x < -9

• x > -9

Solve.

• x ≤ 14

• x < 14

• x ≥ 14

• x = 14
