Question

Given that y varies indirectly as x and that x = 15 when y = 3, then the value of k is​

Answer 1

Explanation:

the equation of this function has the form y = k/x, and when x = 15 and y = 3, the value of k can be calculated as follows:

3 = k/15, or (by multiplying both sides by 15) k = 45

Then y = 45/x
