CLOSED

100

x + 4 < 3 

x < -1

100

2x + 9 > 7

x > -1

100

x + 3x - 4 < 12

x < 4

Is -2 a solution to the inequality?

 4x + 2 < 3

YES!!!

200

Should the circle be open or closed for x > 7?

OPEN

200

5x > -10

x> -2

200

6x - 8 < 10

x < 3

200

-2(x - 3) > 8

x < -1

Which way should you shade the graph?  To the right or the left?

-6 < x

TOP THE RIGHT   -------->

300

x - 8 < 16

x < 24

300

x/6 +7<9

x < 12

What does it mean for the circle on the number line to be open?

An open circle means that the number under the circle is not a possible solution to the inequality.

B: solve inequalities


A roller-skating rink charges a $16 fixed fee plus $7 an hour for a party. Laurie paid $79 to rent the rink. How many hours did she pay to have her party?

16 + 7x = 79
