y =
OD y = 2x

Answer 1

Answer: 5

Explanation:

Answer 2

The answer is

`y = (24)/(x)`

Explanation:

The statement

y varies inversely with x is written as

`y = (k)/(x)`

where k is the constant of proportionality

To find k substitute the values of x and y into the equation

From the question

y = 4

x = 6

We have

`4 = (k)/(6)`

Cross multiply

k = 4 × 6

k = 24

So the formula for the variation is

`y = (24)/(x)`

Hope this helps you
