Question
Divide.
(25x^2 - 40x + 18) div. (5x - 3)
5x - 5 - 3/5x - 3
5x - 8 - 18/5x - 3
5x - 5 + 3/5x - 3
5x - 14
~~~~~~~~~~~~~~~~~~~~~
7x- 14
-------
x - 2
x
7; where x =/ 7
7; where x =/ 2
0
7(x-2)or 7

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

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)
(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
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 :)
4 = k/6
k = 24
so
y = 24/x
Just do what it says :)

THANK YOU DAMON!! YOUR THE BEST!!!
Damon
You are welcome :)
