Given that y varies inversely as x then:
y=k/x
where
k is the constant of proportionality given by:
k=yk
but
y=27 when x=2
thus
k=27×2=54
hence the function will be:
y=54x
The value of x when y is 9 will be:
9=54x
thus
x=9/54
x=1/6
I think the answer is 1/4 + 2x :)
10x=100 because tbh if you Calculate 5x-10=40 it’s give you your answer and go off of that.
