Answer:
46
Step-by-step explanation:
With those problems if you are not given a picture is good we draw one. 
Because an angle bisector forms 2 congruent angles and because is given that  < XVY ≅ < YVW  then 
m < XVY = m < YVW 
       2x+7 = x+15 , subtract x and 7 from both sides to isolate the like terms
       2x-x = 15-7, combine like terms
            x = 8
From the picture and the given we see that 
m < XVW = m < XVY + m < YVW 
 m < XVW = 2x+7 + x+15 , combine like terms
 m < XVW = 3x + 22, substitute x for 8
 m < XVW = 3*8 + 22
 m < XVW = 46
Check our work:
m < XVY =  2x+7  = 2*8 +7 = 16 +7 = 23
m < YVW =  x+15 = 8 +15 = 23
m < XVW = m < XVY + m < YVW = 23+23 =46 
 
        
             
        
        
        
P'(-3,-8) Q'(-6,4) R'(1,-1)
This should be correct! Hope I helped!

Answer:  2/3</h3>
============================================================
Use the slope formula to get that answer
m = (y2-y1)/(x2-x1)
m = (5-1)/(9-3)
m = 4/6
m = 2/3
We have a rise of 2 and a run of 3. 
In other words, we move up 2 and over to the right 3.
