Determine the value(s) for which the rational expression 2x^2/6x is undefined. If there's more than one value, list them separat
Dmitry [639]

Answer:

0

Step-by-step explanation:

Hello, dividing by 0 is not defined. so

\dfrac{2x^2}{6x}

is defined for x different from 0

This being said, we can simplify by 2x

\dfrac{2x^2}{6x}=\dfrac{2x*x}{3*2x}=\dfrac{1}{3}x

and this last expression is defined for any real number x.

Thank you

I really need help. My teacher said that I could use any number.
katen-ka-za [31]
The keyword is Rise over run
So the 2nd y value minus the first y value and divide it by the 2nd x value minus
(y2-y1)/(x2-x1)
(10-7)/5-3)
the first x value and you should get 3/2
*dont worry the if the number is under and not above it’s not a saying to do to the power of but it’s just saying the order in which to put the x and y values.
