Question

The value of x varies with y and when x=1/3 y=12 write an equationto represent the variation

Answer 1

Answer:

y = 36x

Step-by-step explanation:

Given that x and y vary directly then the equation relating the is

y = kx ← k is the constant of variation

To find k use the condition x = $\frac{1}{3}$, y = 12, then

k = $\frac{y}{x}$ = $\frac{12}{\frac{1}{3} }$ = 12 × 3 = 36

y = 36x ← equation of variation
