b
Step-by-step explanation:
735\
Answer:
Option D. 
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line <u>and </u><u><em>the line passes through the origin</em></u>
<u><em>Verify each case</em></u>
case A) we have

Is a equation of the form
The value of k=-2
This equation represent a proportional relationship
case B) we have

Is a equation of the form
The value of k=2
This equation represent a proportional relationship
case C) we have

The line passes through the origin, because the y-intercept is b=0
This equation represent a proportional relationship
case D) we have

The line not passes through the origin, because the y-intercept is not equal to zero (b=2)
This equation not represent a proportional relationship
Answer:
The first option
Step-by-step explanation:

Answer: If the question is to solve for A: A= 
If the question is to solve for B: B= 15x+1-3xA+A
Step-by-step explanation:
A: Move terms to the left.
B: Simplify both sides.
I would say sum because you are adding and it is 11r^3+11
