Answer to Problem 13PPE
Explanation of Solution
Given Information:
The variable y varies inversely with x. The value of y is -10 when x is -2.4 .
Calculation:
Given that the variable y varies inversely with x. So we have
Here k is the constant of proportionality.
Also given that the value of y is -10 when x is -2.4. So, on substituting values of x and y in above equation (i), we get
So, with this value of k , above equation (i) becomes
