Question

If y varies inversely as x, and y = 2 as x = 3, find y for the x-value of 1

Answer 1

Well varying inversely means we use the formula

\[\large y = \frac{k}{x}\] and we need to solve for the constant 'k' first

Answer 2

So, we can take the 2 values known....y=2 when x = 3...so if we plug those into that..

\[\large 2 = \frac{k}{3}\]

what would 'k' equal?
