Inequalities Review

Match the graph with its inequality.

• a > 11

• a < 11

• a ≥ 11

• a ≤ 11

What inequality does the number line graph represent?

• x ≤ 4
• x ≥ -4
• x < -4
• x < 4

You flip an inequality symbol when you...

• subtract
• multiply and divide only
• multiple by a negative number
• multiple or divide by a negative number

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

• <, >
• ≤, ≥ 

Match the graph with its inequality. (HINT: don't be tricked by the variable on the right.)

• 11 < a
• 11 > a
•  11 ≤ a
•  11 ≥ a

Do I need to flip my sign?
-3x  ≥ 12

• Yes
• No

7(2x - 4) = 42

• x= 5
• x= 8
• x= 2
• x= 9

Solve:
2(2x + 3) = -6(x + 9)

• 1.2
• 6
• -6
• 7.5
