Question

I medal...
Suppose y varies inversely with x and x = 12 when y = 3. What is the equation of the inverse variation?

y/x = 36
12 = 3/y
y = 12/3
y = 36/x

Answer 1

Y varies inversely as x means.

y = k/x

where k is the constant of variation.

Use the x and y value they gave you to figure out what the k value is

Answer 2

\[3 = \frac{ k }{ 12 }\]

Answer 3

Then use that k value in:

\[y = \frac{ k }{ x }\]

for your final answer

Answer 4

\[y = \frac{ 12 * 3 }{ x }\]
