6/3.5 = 14.875/x
6 x 14.875 = 89.25 
89.25/3.5 = 25.5
        
             
        
        
        
Answer:
2/3x
Step-by-step explanation:
This is a simple ax graph. all we need is the slope. the slope is the amount the y goes divided by the amount the x goes. essentially 
change in y / change in x
2/3
2/3x
 
        
                    
             
        
        
        
From angle bisector theorem, we know that:

Moreover:

so:

and
 
 
        
        
        
Answer:
B
if f(x-4) then we should put x-4 where the x is spouse to be so;
-2(x-4)-1 =
-2x + 8 - 1 =
-2x + 7
