Answer:
p ≈ 19.19 %
Step-by-step explanation:
198 - p×198/100 = 160
19800 - 198p = 16000
19800 - 16000 = 198p
3800 = 198p
p = 19.19 %
B) is the answer hope this helps
Answer:
4x + 18
Step-by-step explanation:
This is called a composite function, meaning passing the range of one function as a domain of another function.
For f(f(x)), the inner-function's range is passed as the domain of the outer function.
We can do so by substitution,
The range of f(x) can be written as 2x + 6 for any defined x values,
So we will substitute 2x + 6 as the 'x' of another function which is in this case
f(x) again, so it looks like this 2(2x+6) + 6 which can be simplified into
4x + 18
