Answer:
(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
Answer:
It's A I think
Step-by-step explanation:
I guessed
P(Failure on first try) = 11/12
P(Failure on second try) = 10/11
P(Failure on third try)= 9/10
P(success on fourth try) = 1/9
P(success exactly on fourth try) = 11/12*10/11*9/10*1/9 = 1/12
The answer is 1/3 on the number line
