Re: Inverse Variation Problem
Hi Spanky;
When y varies inversely with x we maen:
y = k / x or xy = k. Now you say k = - 20, so we have:
26 x = - 20
x = - 20 / 26
In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.
