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:
A and E
When doing problems like these it is easier just to see what numbers are divisbale by the ration.
Example:
A: 21/30
21 is divisable by 7 and 30 is divisbale by 10
E: 35/50
35 is divisable by 7 and 50 is divisbale by 10
Answer:
The correct option is D.
Step-by-step explanation:
It is given that Issouf claims that the scale factor is 1/2.
From the given figure it is clear that



The scale factor of a figure is




The scale factor is 1/3 because CB is actually 2 + 4 = 6.
Therefore the correct option is D.
