What is the first step to solve this equation?
x - 5 = 7 - 2x 

• Add 7 to both sides of the equation

• Add 2x to both sides of the equation

• Subtract 2x from both sides of the equation

• Subtract 5 from both sides of the equation

• (m+10)(m-9)

• (m-10)(m-9)

• (m-10)(m+9)

• 
  (m+10)(m+9)

Is the set of relation a function and how can you tell

Relation: {(4,7), (5,9), (8,5), (5,2)}

• Yes its a function cause all the numbers have lines

• No it's not a function because there a 5 in both ovals

• No it's not a function because the x value 5 has 2 outputs.

• No it's not a function because the y value 5 has 2 inputs.
