Answer:

Step-by-step explanation:
If x varies directly as the product of p and m, and inversely with y, the relation can be written ...
x = k(pm)/y . . . . where k is the constant of proportionality
__
This can be solved for k:
k = xy/pm
For the given values, the value of k is ...
k = (2)(4)/((0.5)(2)) = 8
Then the relation between the variables can be written ...
(xy)/(pm) = 8
Equation of the line:
y = -1.5x – 9
or
y =
- 3 x
2
– -9
When x=0, y = -9
When y=0, x = -6

Answer: OPTION C.
Step-by-step explanation:
In order to solve the given exercise, you can follow these steps:
1. Given the following function f(x):

You must substitute
into the function f(x). Then:

2. Evaluating, you get:

3. Now, the next step is to substitute
into the function g(x):

4. Finally, evaluating, you get the following result:

You can identify that it matches with the Option C.
15-2x=3x
Add 2x to both sides
15=5x
Divide by 5 on both sides
3=x
