Answer:
D 8 hours
Step-by-step explanation:
it has to be positive and it is obviously more than 1 hour so it has to be 8 hours by process of elimination.
to get the mixed number just divide the numerator by the denominator;
55 ÷ 3 = 18 1/3
Simply substitute the value of
3
given. In other words,
f
(
3
)
is the function of
f
(
x
)
, however, in this case,
x
is
3
f
(
3
)
=
3
(
3
)
−
4
Distribute
3
through the parenthesis
f
(
3
)
=
9
−

Simplify
f
(
3
)
=
