Inequalities

When do you "flip the inequalities sign"?

• When you add or subtract a negative

• When it's a 1-step problem

• When you multiply or divide a negative

• When it's a 2-step problem

-3x ≤ 18

• x ≤ -6

• x ≤ 6

• x ≥ 6

• x ≥ -6

Solve 5x + 9 > 34

• x > -5

• x > 5

• x < -5

• x < 5

Solve -2x - 3 ≤ 13

• x ≥ 8

• x ≥ -8

• x ≤ 8

• x ≤ -8

When do you use a closed circle on a graph for an inequality?

• When it is ≥ or ≤

• When it is > or <

• When the number in front of the variable is negative

• When it is only =

Match the graph with its inequality.

• a > 11

• a < 11

• a ≥ 11

• a ≤ 11

Pick the correct letter for:

x < 6

• A

• B

• C

• D

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

• <, >

• ≤, ≥

6 - 2h > 30

• h < 24

• 18 > h

• h > 12

• h < -12

Solve.

• x ≤ 14
• x < 14
• x ≥ 14
• x = 14
