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

• ≤, ≥

• <, >

x + 5 ≤ 13

• x ≥ 8

• x ≥ 18

• x ≤ 8

• x ≤ 18

Describe the graph for the solution for the following inequality:
a + 13 ≥ 20

• Closed circle; arrow pointing left

• Open circle; arrow pointing left

• Closed circle; arrow pointing right

• Open circle; arrow pointing left

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.
