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>
Answer:
D. 740
Step-by-step explanation:
Put the given value of b into the formula and do the arithmetic:
A(150) = 5×150 -10 = 750 -10
A(150) = 740
The band raised $740 from their sales.
25.05 I would think mean .05 is the change and if there is not a month cost than it would not double
Answer:
x = 30
Step-by-step explanation:
In order for the lines to be parallel,
2x + 20 = 80
2x = 60
x = 30
Answer:
B) -7
Step-by-step explanation:
x+y
8+(-15)=8-15=-7
