Answer:
y = 1
Step-by-step explanation:
Given that y varies inversely with x then the equation relating them is
y = 
← k is the constant of variation
To find k use the condition y = 25 when x = 
, then
25 = 
= 5k ( divide both sides by 5 )
5 = k
y = 
← equation of variation
When x = 5, then
y = 
= 1
