The value of x when y = 9 is x = 2 or x = -2
Solution:
Given that value of y varies inversely as the square of x, and y=4, when x=3.
Therefore the initial statement is:
To convert to an equation, multiply by k, the constant of variation
--- eqn 1
Given that,
y = 4 when x = 3
Now find value of k
Find the value of x when y = 9
x = ?
y = 9
From eqn 1,
Thus value of x is found
