Choose any numbers that are less than or equal to -3.5 OR greater than -2.5. (In this case, a number can't be both, but can be one or the other!)

• -4

• -3.5

• -3

• -2.5

Choose any numbers that are greater than 5 AND less than 10.

• 4

• 6

• 8

• 10

• x > -3 or x > 1

• x < -3 or x < 1

• x ≥ 3 and x ≤ 1

• x > -3 and x < 1

• x ≤ 3 and x > -2

• x < -2 or x ≥ 3

• x > -2 or x < 3

• x < 3 and x ≥ -2

• x < 0 or x ≥ 2

• x < 0 or x > 2

• x ≤ 0 or x ≥ 2

• x ≤ 0 or x > 2

What inequality is shown?

• x ≥ -5 OR x < 4
• x ≤ -5 OR x > 4
• -5 ≤ x < 4
• -5 ≥ x > 4

What inequality is shown?
Pay close attention to the signs!

• x ≥ 0 OR x < 5
• 0 ≤ x ≤ 5
• 0 ≤ x < 5
• 0 ≥ x > 5
