Do Now Write an inequality for each sentence. (If you need help use p. 234 and 235 in your book)

Fido weighs more than 15 pounds.

The room’s capacity is at most 500 people.

ObjectiveSWBAT access and apply objectives from lessons 5.3 and 5.4.

Write an inequality for each sentence.

1.The weight of adult male elephant is greater than 12,000 pounds.

2.The 10km race time was at least 84 minutes.

3.The savings account has no more than $400.

4.The maximum fee for any student is $15.

Graph an Inequality

A. Graph x > 10 on a number line.

Locate 10 on a number line. Draw an open dot on 10 because 10 is not included.

Draw an arrow to the right.

The inequality x > 10 means that all numbers greater than 10 will make the sentence true.

Graph an Inequality

B. Graph x 10 on a number line.

Locate 10 on a number line. Draw a closed dot on 10 because 10 is included.

Draw an arrow to the left.

The inequality x ≤ 10 means that all numbers less than or equal to 10 will make the sentence true.

Example 5Write an Inequality

Write an inequality for the graph.

A closed circle is on –38, so the point –38 is included in the graph. The arrow points to the right, so the graph includes all numbers greater than or equal to –38.

Answer: The inequality is x ≥ –38.

A. AB. BC. CD. D

Example 5

A. x < –7

B. x > –7

C. x ≤ –7

D. x ≥ –7

Write an inequality for the graph.

1. Graph x < -12 on a number line.

1. Graph x ≥ -1 on a number line.

1. Write an inequality to represent the graph.
