Exploring Multi-step Inequalities

What is the first step in the 'Don't Call Me After Midnight' method?

• Graph the solution

• Move variables

• Distribute

• Combine like terms

In the example, what is the result of distributing -2 to (a - 7)?

• 2a + 14

• -2a + 14

• -2a - 14

• 2a - 14

What do you do after combining like terms in a multi-step inequality?

• Graph the solution

• Distribute

• Use inverse operations

• Move variables

When must you flip the inequality sign?

• When adding a negative number

• When combining like terms

• When subtracting a positive number

• When multiplying or dividing by a negative number

What is the final inequality after solving -5a + 14 ≥ -31?

• a ≥ 9

• a ≥ -9

• a ≤ -9

• a ≤ 9

How do you represent the solution of an inequality on a number line?

• With a shaded region above the number

• With a closed circle on the number

• With a shaded region below the number

• With an open circle on the number

What does a closed circle on a number line indicate?

• The number is not included in the solution

• The inequality is strict

• The inequality is not strict

• The number is included in the solution

In the second example, what is the result of combining 4y and 4y?

• 0

• 8y

• 4y

• 16y

What is the final inequality after solving 8y + 11 ≥ 43?

• y ≥ 4

• y ≤ 4

• y ≥ -4

• y ≤ -4

What should students bring to the teacher for credit?

• Their textbook

• Their notebook with problems 9, 11, and 14 solved

• A completed worksheet

• A graph of the solutions
