Question

Write an inverse variation equation that relates x and y. With x being 10 and y being 2

Answer 1

Answer:x=20/y

Explanation:

x α 1/y

removing the constant of proportionality sign α and replace it with =k

x = k/y

x=10 y=2

10 = k/2

Cross multiply

10x2=k

20=k

k=20

Substitute k=20 in x=k/y

x=20/y.........required equation
