Answer:
f=2
Step-by-step explanation:
0.3+0.5f-0.7
Move the varibale (0.5f) to the left-hand side and change it's sign to negative.
-0.5+0.3+-0.7
Move the constant to the right hand side and change it's sign
-0.5f=-0.7-0.3
Calulate the differnce
-0.5f=-1
divide both sides by -0.5
F=2
We are given the functions:
P (x) = 0.9 x
C (x) = x – 150
We can generate two composition functions from the given
two functions in the form of:
<span>P [C (x)] and
C [P (x)]</span>
Since the problem states that we are to find for the final
price after a 10% discount is followed by a $150 coupon then we should
find for:
C [P (x)]
The value of C [P (x)] can obtained by plugging in the
value of P (x) into x in the equation of C (x), therefore:
C [P (x)] = [0.9 x] – 150
<span>C [P (x)] = 0.9 x – 150 (ANSWER)</span>
Huh... In school, I was taught that those angles are Supplementary... But the answer is B.
