OH! haha I was writing something sorry didn't see it thanks!
Damon
7(x-2) /(x-2) = 7 * 1 = 7
but x may not be 2 or the original denominator would be zero
This Girl
The first one is C right?
This Girl
So is the answer for the second one 0?
This Girl
wait no, it is B, 7; where x =/ 7?
Damon
7 where x not equal to 2

(x=2 is not in the domain, function undefined there)
This Girl
So C again?
This Girl
and could ask one last question?
Damon
I guess C
which is
7; where x =/ 2
assuming that x=/2 means not when x = 2
This Girl
okay sweet thank you SO MUCH! You should be a teacher man, you would be an EXCELLENT ONE!!
This Girl
Could I ask you one more question please?
Damon
LOL, many years ago.
This Girl
haha here's my last question

Suppose that y varies inversely with x and that y = 4 when x = 6. What is an equation for the inverse varition?

y = 6/4x

y = 24/x

y = 2/3x

y = x/24
Damon
y = k/x

4 = k/6

k = 24
so
y = 24/x

Just do what it says :)
This Girl
THANK YOU DAMON!! YOUR THE BEST!!!
