Solving Inequalities Substitution

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

• <, >
• ≤, ≥ 

Match the graph with its inequality.

• 11 < a
• 11 > a
•  11 ≤ a
•  11 ≥ a

Do I need to flip my sign when I solve this inequality?
3x  ≥ 12

• Yes
• No

Solve:  
4b + 6 ≤ 18

• b ≥ 3
• b ≤ 3
• b ≥ 48
• b ≤ 48

Solve the following inequality:
-4x + 14 ≤ 54

• x ≥ -10
• x ≤ -10

• x ≤ 10

Solve:
-4(-7-5x) > 188

• x < -32
• x > -32
• x < 8
• x > 8

Solve:

• p ≤ -12
• p ≥ -12
• 20 ≥ p
