Answer:

Explanation:

(a)

Y = k / √x where k is a constant.

When x = 9 , y= 2 so:

2 = k / √9

k = 2√9

k = 6

So the answer is

y = 6/√x.

(b)

When x = 36,

y = 6 / √36

= 6/6

y = 1.

(c)

y = 6/√x

y * x = 6

x = 6/ y

x = 36/y^2

(d)

Let's take x = 9 and y = 2

New x = kx = 9k

New y = 2*0.5 = 1

So,

9k = 36 / 1^2

k = 36/9

k = 4.
