Answer:
   16
Step-by-step explanation:
Put the numbers where the variables are and evaluate:
   F(3) = 2(3)^2 +1 = 19
   G(4) = 2(4) -1 = 7
   H(5) = 5
Then the desired sum is ...
   F(3) +G(4) -2H(5) = 19 +7 -2(5) = 16
 
        
             
        
        
        
C, because when you add 45 on both sides, and then after that when you have to subtract 15 in both sides, you get 0 = 120.
 
        
             
        
        
        
Y=-3/2x+4 
The slope is -3/2, since Kerry traveled three feet and only went down 2. 
The y intercept is 4, since she started four feet above the origin
