Solving Inequalities

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

• <, >

• ≤, ≥ 

When you graph an inequality, you used a closed dot when you use which symbols?

• ≤, ≥ 

• <, >

Match the graph with its inequality.

• 11 < a

• 11 > a

•  11 ≤ a

•  11 ≥ a

- 2k > 18

• k is greater than 20

• k is less than negative 9

• k is greater than negative 9

• k is less than 36 

6 + 2h > 30

• h < 24

• 18 > h

• h > 12

• h < -12

7b - 3 < 11

• b < 2

• 84 > b

• b > 2

• b < 84

4x - 3 < -1x + 12

• x > 3

• x < 3

• x < 5

• x > 5

Solve and choose the correct graph:

• A

• B

• C

• D

-1(2x + 4) ≥ 6

• x ≤ -5

• x ≥ -5

• x ≤ -1

• x ≥ -1

Solve 24 > -3r > -9 

• -8 < r < 3

• -8 > r > 3

• r > - 8 and r > 3 

• r > -8 or r < 3
