Pick the correct inequality.

• A

• B

• C

• D

x + 5 ≤ 13

• x ≥ 8

• x ≥ 18

• x ≤ 8

• x ≤ 18

What are two solutions to x < 8?

• 8.6, 7.9

• 11, 16

• 0.8, 5.9

• 12, 7.1

8.9 + j = 12.8

• j = 21.7

• j = 3.9

• j = 1.4

• j = 4.1

Write an equation for the model above.

When graphing an inequality, you use a closed circle when you use which symbols?

The variable, k, is being divided by 11. How should you isolate the variable? ​  

• Divide both sides by 11

• Add 11 to both sides.

• Multiply both sides by 11.

• Subtract 11 to both sides.
