Question

suppose that y varies inversely with x, and y=3 when x=10. Write an inverse variation equation that relates x and y. Find y when x = 5

Answer 1

equation for inverse variation is \[\huge\rm y = \frac{ k }{ x }\]
so first replace and y by their values and solve for k

Answer 2

x and y**

Answer 3

y=3 when x=10. replace y by 3 and x by 10 and solve for k :)
