Question

if y and y vary inversely and y = 45. Find x when constant of variation = 9.​

Answer 1

Answer:

Since x and y vary inversely

therefore

xy=k( constant)

45x=9

x=9/45=1/5

Answer 2

Answer:

$x = \frac{1}{5}$

Step-by-step explanation:

I think you mean y and x very inversely.

Quantities x and y are said to vary in inversely proportional if

xy = k

k is constant

where y = 45, k = 9

Apply the the values

xy = k

$x * y = k\\x * 45 = 9\\45x = 9$

Divide both sides by 45

$\frac{45x}{45} = \frac{9}{45} \\x = \frac{1}{5}$

Therefore; $x = \frac{1}{5}$

Hope this helps.
