How do I solve these problems?

f(x)*g(x)

f(x)/f(x)

How do i solve these problems?

f(x)*g(x)

f(x)/f(x)
Solve what? I see nothing to solve. Except, perhaps, f(x)/f(x)=1.

Define some functions and we'll see what we can do.

if y varies inversely as x,and y =12 when x=6, what is k, the variation constant

if y varies inversely as x, and y=12 when x=6,what is k, the variation constant

if y varies inversely as x,and y=12 when x=6,what is k,the variation constant

Please do not hijack someone else's post. Create your own thread.

Also, there's no need to post the same problem 3 times.

Anyway, y varies inversely as x: y=\frac{k}{x}

Solve for k. You're given x and y.
