Question

If x varies inversely as y and x = 4 when y = 6, when x = 3, then value of y is _________ plz answer fast I am writing test

Answer 1

Answer:

8

Step-by-step explanation:

x ∝ 1/y

when x = 4, y = 6

Now, xy = k

=) 4 * 6 = k

=) 24 = k

Now,

x = k/y

=) y = k/x

=) y = 24 / 3

( As k is constant i.e. it never changes, so we should solve it by keeping the value of k constant)

=) y = 8

Hence, y = 8.
