F(x) = 2x and g(x) = 2x - 7
Find (f - g)(x).

(f-g)(x)=7

Step-by-step explanation:

f(x)=2x

g(x)=2x-7

(f-g)(x)=f(x)-g(x)=2x-(2x-7)=7

step-by-step explanation:

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
