What is the answer for this problem? if f(x)=3x-1 and g(x)=x+2, find (f-g)(x) a. 3-2x b. 2x-1 c. 4x+1 d. 2x-3

This is a problem involving the subtraction of two functions f(x) and g(x):

if f(x)=3x-1 and g(x)=x+2, find (f-g)(x).  In other words, find:

  f(x)  = 3x-1 
-{g(x) -(x+2)

f(x) - g(x) = 3x - 1 - x - 2 = 2x - 3  (answer)

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
