Algebra 1A - 11/5

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

• ≤, ≥

• <, >

Match the graph with its inequality.

• 11 < a

• 11 > a

• 11 ≤ a

• 11 ≥ a

When graphing an inequality, you use an open dot when you use which symbol?

• <, >

• ≤, ≥

10 ≥ x - 3

• x ≤ 13

• x ≥ 13

• x ≤ 7

• x ≥ 7

4x - 2 ≤ -22

• x ≥ -5

• x ≥ -6

• x ≤ -6

• x ≤ -5

When do you need to flip the symbol of an inequality?

• when you add both sides by a negative value

• when you subtract both sides by a negative value

• when you divide both sides by a negative value

6(n + 2) < -72

• n < -14
• n < 35/3
• n < -10
• n > -14

6x + 10 > 5x - 12

• x > 2
• x < -2
• x < -22
• x > -22

Do I need to flip my sign?
-3x  ≥ 12

• Yes
• No
