Question

Y varies inversely with x, when y is 48 when x is 1/3 .which equation represents this situation?

Answer 1

Answer:

A

Step-by-step explanation:

Given that y varies inversely with x then the equation relating them is

y = $\frac{k}{x}$

To find k use the condition y = 48 when x = $\frac{1}{3}$, thus

k = yx = 48 × $\frac{1}{3}$ = 16

y = $\frac{16}{x}$ ← equation of variation
