Multiple Select

What are the two inequalities that were written in the previous video?

• $2h+3c\le30$

• $h\ge3$

• $3h+2c<30$

• $h<3$

Guided Notes:

• Remember <> signs when graphed are shown by a dotted line.

• The  $\le\ge$  signs have a solid line on a graph. 

• You shade in the direction of the inequality. 

•  $<\&\le$ Shade Downwards

•  $>\&\ge$  Shade Upwards

• Where the shading crosses in the solution to the system.
