Question

Given that y varies inversely as x, use x = 3.3 and y = 15 to find an equation that relates them. A) y = 4.6875x B) y = 16 75 x C) y = 16.75 x D) y = 49.5 x E) y = 48x

Answer 1

we know that

if y varies inversely as x----------> the equation is y=k/x
where
k--------> is the constant of variation

for x=3.3 y=15
then
y=k/x--------> 15=k/3.3---------> k=15*3.3--------> k=49.5
so
y=49.5/x

the answer is
y=49.5/x
