Open or Close Inequality

What inequality is graphed? 

• x > 2 and x ≤ -3

• x > 2 and x < -3

• x > 2 or x ≤ -3

• x > 2 or x < -3

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

What would be the first step in solving the inequality for 2x+7>15?

• Add 7 to both sides

• Subtract 7 from both sides

• Divide both sides by 2
