Question

0 If x and y vary inversely and y=6 as x=7, what is the constant of variation?

Answer 1

Answer:

k = 42

Step-by-step explanation:

given that x and y vary inversely then the equation connecting them is

y = $\frac{k}{x}$ ← k is the constant of variation

To find k use the condition y = 6 when x = 7

k = yx = 6 × 7 = 42
