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

• ≤, ≥

• <, >

Which inequality matches the graph?

• A

• B

• C

• D

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.

8.9 + j = 12.8

• j = 21.7

• j = 1.4

• j = 3.9

• j = 4.1

Describe the graph for the solution for the following inequality:

a + 13 ≥ 20

• Closed circle; arrow pointing left

• Closed circle; arrow pointing right

• Open circle; arrow pointing left

• Open circle; arrow pointing left

The objective when solving an equation is to....

• isolate the variable.
• check the solution.
• guess and check.
• Combine Like Terms.
