15x=45
45/15 =3 
X=3 
45 miles in 3 hours 
How long did it take for 40 miles? 
15x=40 
40/15 = 2.6666667 
15 x 2= 30 
15 x 2.5 = 37.5 
15 x 2.6 = 39 
15 x 2.7 = 40.5 
1 hour equals 60 mins

Answer:
   7)  (f+g)(x) = 4^x +5x -5
   8)  (f-g)(x) = 4^x +x +5
Step-by-step explanation:
7) add the two expressions.
   (f+g)(x) = f(x) +g(x) = (4^x +3x) +(2x -5)
   (f+g)(x) = 4^x +5x -5
__
8) subtract g(x) from f(x).
   (f-g)(x) = f(x) -g(x) = (4^x +3x) -(2x -5) = 4^x +3x -2x +5
   (f-g)(x) = 4^x +x +5
 
        
             
        
        
        
Answer:
The leading term is 2x^7. Since n is odd and a is positive, the end behavior is down and up.
