Answer:
17
Step-by-step explanation:
f(x) = 3x + 2
Let x=5
f(5) = 3*5 + 2
Multiply first
     = 15+2
Then add
     = 17
 
        
                    
             
        
        
        
Answer: m= -2
               b= 14
               y= -2x+14
Step-by-step explanation:
First, you estimate to find the m. After you get -2, you plug the numbers in, and see what you add to get x.

Answer:
If solving for x then x = -3/2 +y/2
If solving for y then y = -3-2x
Step-by-step explanation:
For x: Divide both sides by 2 
For y: Subtract 2x from both sides of the equation
