For the equation -4y = 8x , what is the constant of variation?
2 answers:
Answer: B: -2
Step-by-step explanation:
Given equation:
To make it in standard form divide both sides by -4, we get
Now this is in the standard form of y = mx, where m is the constant of variation.
Thus, the constant of variation is -2.
<em>The constant of variation (m) is the number that associates two variables that are directly proportional or inversely proportional to each another. </em>

Answer:
125,000,000
Step-by-step explanation:
In percentage,
Media + Sales = 3 + 17 = 20%
Let total budget be "t", so we can say:
20% of total budget is 25,000,000
"of" means "multiplication" and "is" means "equal to", so we can convert word equation to algebraic equation. Shown below:
20% * t = 25,000,000
20% = 20/100 = 0.2
Thus, the final equation is:
0.2t = 25,000,000
Solving for t, we get:
The total budget is (125 million) = 125,000,000
