The value of x when y = 4 is 0. 25

How to determine the value

From the information given, we have that;

  • x varies directly as y
  • x also varies partly as y²

This is expressed as;

x ∝ 1/ y²

x = y/y²

Let's substitute the value of y as 4 into the equation;

x = 4 / 4²

Find the square

x = 4 / 16

Find the ratio

x = 1/ 4

x = 0. 25

Thus, the value of x when y = 4 is 0. 25
