Answer:

21

Step-by-step explanation:

The given equation of Inverse Equation is ,

[tex]\implies xy = k [/tex]

We need to find the value of k , when x = 7 and y = 3 . For that substituting the respective values in the equation , we have ,

[tex]\implies 7\times 3 = k \\\\\implies\underline{\underline{ k = 21}} [/tex]

Hence the required answer is 21.

Step-by-step explanation:

xy=k

Now, by putting the values, we get

xy=k

7×3=j

21=k

Hence, option d is correct
