You could do x=81 with the little line on the top (represents the number going on forever, and example is 0.818181818181818181818181818818181818 etc.)
First of all, you should know that:
direct variation:
y = c * x
Inverse variation:
y = c / x
where, c is any number that belongs to the real ones.
answer:
An equation that represents an inverse variation is
y = 4 / x
Answer:
Step-by-step explanation:
Answer:
y=-2.4y
Step-by-step explanation:
First you want to restate the problem.
-3(y+3)=2y+3
Now distribute the negative.
-3y-9=2y+3
Add 3y to both sides.
-9=5y+3
Subtract 3 from both sides.
-12=5y
And solve.
-2.4=y
Answer:
constant of proportionality
Step-by-step explanation:
Assuming that we have two proportional quantities; one is x and one is y.
If we know whether the relationship between them is direct or inverse proportion, then the ratio of the two quantities y/x gives us a constant generally known as the constant of proportionality.
