14^10. Minus the powers 15 - 10
The equation is y = 63/x
And y = 3 when x=21
Step-by-step explanation:
When y varies inversely with x, The inverse proportion is given by:
y ∝1/x
When the proportionality symbol is removed, a constant of proportionality is introduced

Putting y = 7 and x = 9

So,

Putting x =21

Hence,
The equation is y = 63/x
And y = 3 when x=21
