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 room can hold a maximum of 400 people. If there are already 134 people there, how many more can come? Identify the inequality that represents this situation.

• x - 134 < 400

• x + 134 < 400

• x - 134 ≤ 400

• x + 134 ≤ 400
