Learning Inequalities

Write the inequality in sandwich notation: x > 4 and x < 12

• 4 > x > 12

• 4 < x < 12

• 4 > x > 12

• 12 < x < 4

Penelope is going to the carnival to ride the rides. It costs $20 to get into the carnival and ride tickets are $0.50 each. Write an equation that represents this scenario if she can spend no more than $35 in all.

• .50x + 20 ≥ 35

• .50x < 35

• .50x + 20 ≤ 35

• .50x - 20 = 35

Write the following solution in interval notation:

• [ -3, +∞ )

• ( -3, +∞ )

• ( -∞ , -3 )

• ( -∞ , -3]

| -8x | < 8

What is the correct first step?

• separate into two inequalities with an "and"

• separate into two inequalities with an "or"

• divide both sides by -8

• add 8 to both sides

| x - 6 | < 4
Is this an "and"  or an "or" problem?

• and

• or

| x - 2 | > 3
Is this an "and"  or an "or" problem?

• and

• or
