Answer:
False
Step-by-step explanation:
40c - 300 = 40c + 200
-300 = 200
false
Answer:
<em>y=-6</em>
Step-by-step explanation:
<u>Proportions</u>
A direct proportion is a relation between variables where their ratio is a constant value. This means that if y and x are proportional, then:
y = kx
Where k is the constant of proportionality.
Substituting x=-3 y=9:
9 = k(-3)

Now the relationship is:
y = -3x
For x=2
y = -3(2) = -6
Answer:
Choice B
Step-by-step explanation:
Choice B is not a proportional relationship because it is not in the form of Y = KX.
First, you must convert the equation, X - Y = 2 to Y = MX + B by subtracting X to the right side to get -Y = -X +2. Then divide each side by -1 to get a positive Y value. Then you are left with Y = X - 2, which is not in the form of Y=KX.
