X equals five plus or minus the square root of negative five squared minus four times two times eighteen, all divided by two times two
Answer:
Set 1) A and B are proportional because it is in the form of y = kx
Set 2) B is proportional because it is a straight line passing through the origin
Set 3) B and C because it uses the equation y = kx

Answer:
a) 
b) 
Step-by-step explanation:
We are given:
We need to find 
a) First finding: 
It can be found by putting the value of g(x) into f(x)
We are given:
SO, we get:
b) Now finding: 
It can be found by putting x=9 in f(g(x))
We have:
So, we get:
Using proportions, it is found that the amount owed for each bill are given as follows:
$31.33 for food $9.90 for alcohol.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount.
In this problem, each of the bills are split equally among the five people, hence the fraction is 1/5.
Thus:
1/5 x 156.65 = $31.33
1/5 x 49.50 = $9.90.
Hence the amount owed for each bill are given as follows:
$31.33 for food $9.90 for alcohol.
