What is the multiplication property of equalities

• When you multiply the terms inside a parentheses by the term outside the parenthesis

• When you multiply both sides of the equation by the same term

• When you multiply like terms together

• When you multiply one side of the equation

 $\times>9$  What value for x would make the following inequality true:

• 9

• -10

• 5

• 11

 $2\left(x+9\right)-32=5x+9$  What would be your next move in the following equation:

• combine x and 9 into 9x

• subtract 4x on both sides

• Combine 9 and -32

• Distribute the 2

 What would be the next two steps in the to solve the following equation: $2x-7=5x+8$ 

• Subtract 2x from both sides and then subtract 8 from both sides

• Add 5x to both sides and then subtract 7 from both sides

• Subtract 5x from both sides and then subtract 8 from both sides

• Subtract 2x from both sides then add 7 to both sides

Which is the correct inequality for the graph above

•  $x<-4$  

•  $x>-4$  

•  $x\ge-4$  

•  $x\le4$

Which is the correct compound inequality

• $5<x\le9$

• $x<5\ or\ x\ge9$

• $5>x\ge9$

• $x<5\ or\ x\le9$

What mistake was made below:
 $5\left(x+1\right)-9=10$  
 $5x+1-9=10$  
 $5x-8=10$  
 $5x=18$  
 $x=\frac{18}{5}$  

• There is no error

• In Step 5 you didn't divide properly

• In step 3 you didn't combine like terms correctly

• In step 1 you didn't multiply 1 by 5
