• x > 5
• x ≤ 5

Write x ≤ 23 in words.

• x is greater than 23

• x is greater than or equal to 23

• x is less than 23

• x is less than or equal to 23

Write x > 7 in words.

• x is greater than 7

• x is less than 7

• x is less than or equal to 7

Ashley sees a sign that says you must be more than 48 inches tall to ride a roller coaster.

She writes the inequality as h > 48.

How can she graph the solutions of the inequality?

• Plot an open circle at 48 and shade left.

• Plot a closed circle at 48 and shade left.

• Plot an open circle at 48 and shade right.

• Plot a closed circle at 48 and shade right.

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

• <, >

• ≤, ≥

• ≤, <

• ≥, >
