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

When do we switch the inequality symbol?

• when multiplying or dividing by a NEGATIVE

• when adding and subtracting a NEGATIVE

• we never switch the inequality

• When there is a negative in the problem
