One Step Inequality Practice

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

What are two solutions to x < 8?

• 8.6, 7.9

• 11, 16

• 0.8, 5.9

• 12, 7.1

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

When you graph an inequality, you use a closed dot when you use which symbols?

• ≤, ≥ 

• <, >

• ≤, <

• ≥, >

Do I need to flip my sign?
3x  ≥ 12

• Yes

• No

• -84 ≥ k

• k ≤ 84

• k ≥ 84

• k ≥ -84

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

Amira wrote the inequality p + 5 ≤ 18. Which situation is best represented by this inequality?

• Amira spent 18 minutes making p phone calls. Each call was at least 5 minutes long.

• Amira removed 18 marbles from a bag of p marbles. Afterwards, there were at least 5 marbles in the bag.

• Amira placed p pieces of paper in 18 stacks. Each sack had a most 5 pieces of paper.

• After Amira added 5 books to a stack of p books, there were no more than 18 books in the stack.

Write an inequality for this situation:
You are driving, and the maximum speed limit is 55.

• s ≥ 55

What inequality does the number line graph represent?

• x≥ 3

• x > 3

• x < -3

• x ≤ 3
