The value of y when x= 2401 is -10
<h3>How to determine the value of x?</h3>An inverse variation is represented as:
Where k is the proportionality constant
When y = -70, x = 49
So, we have:
Take the square root of 49
Multiply through by 7
k = -490
Substitute k = -490 in
When x =2401, we have
Evaluate the square root
Divide
y = -10
Hence, the value of y when x= 2401 is -10
