Solve:

 $-16\le2x<20$  .  Choose the correct solution set.  (Pick all that apply!)

•  $-8\le x<10$  

•  $-8<x\le10$  

•  $x\ge-8\ and\ x<10$  

•  $x\ge-8\ or\ x<10$  

•  $x>10\ and\ x\le-8$  

Write the inequality for this graph.

• $x<5\ \ \ or\ \ \ x\ge7$

• $x<5\ \ \ and\ \ \ x\ \ge7$
  

• $x\le5\ \ \ and\ \ \ x>7$

• $x\le5\ \ \ or\ \ \ x>7$

Solve. Then describe the graph.

 $\left|2x-12\right|<10$  

• The graph would include an open circle at 10 and 1 and would be shaded between. 

• The graph would include an open circle at 1 and 11 and would be shaded between. 

• The graph would include an open circle at 1 and 11 and would be shaded toward the ends of the number line.

• The graph would include a closed circle at 1 and 10 and would be shaded between.

• x < -7
