Solving Inequalities

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

• <, >
• ≤, ≥ 
• ≤, <
• ≥, >

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

• ≤, ≥ 
• <, >
• ≤, <
• ≥, >

• x is less than or equal to -2
• x < -2
• -2 < x
• x is greater than -2

Match the graph with its inequality.

• 11 < a
• 11 > a
•  11 ≤ a
•  11 ≥ a

Which inequality matches the graph?

• x<3

• x>3

• x<3

• x>3

When the following inequality is graphed, what will it look like?

2 > f

• open circle

• closed circle

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

2x > 12

• x > 6

• x < 6

• x ≥ 6

• x ≤ 6

-3x ≤ 18

• x ≤ -6

• x ≤ 6

• x ≥ -6

Solve 3x + 7 < 22

• x < -29/3

• x < -5

• x < 29/3
