Answer:
y = 150
Step-by-step explanation:
Given that y varies inversely as x² then the equation relating them is
y = ← k is the constant of variation
To find k use the condition y = 6 when x = 30 , then
6 = = ( multiply both sides by 900 )
5400 = k
y = ← equation of variation
When x = 6 , then
y = = = 150
