Solving Inequalities

Solve the inequality.
x + 5 ≤ 13

• x ≥ 8
• x ≥ 18
• x ≤ 8 
• x ≤ 18 

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

Is x = 9 a solution to the given inequality.
x > 9

• TRUE
• FALSE

Is x = 12 a given solution to the inequality.
x > 5

• TRUE
• FALSE

What inequality does the number line graph represent. 

• x < 2
• x > 2
• x ≥ 2
• x ≤ 2

x + 5 > 7

• x > -2
• x > 2
• x > 12
• x > -12

-8x < 48

• x < -6
• x > -6
• x < 6
• x > 6

• x > 3

• x ≤ ⅕

• x ≥ 3

• x ≤ ⅕

Do I need to flip my sign?
-3x  ≥ 12

• Yes, because I'll be dividing by a negative number
• No, because you never flip the sign.
