Question

What is the value of the rational expression 3-x/x-6​ when x is equal to 9?

Answer 1

Answer:

$\boxed{\sf \ \ \ answer \ \ B \ \ \ }$

Step-by-step explanation:

Hello,

x is like a container, it can contain any real number

in that case we need to replace x by 9

so we need to compute the following

$\dfrac{3-x}{x-6} \ for \ x =9\\\dfrac{3-9}{9-6}=\dfrac{-6}{3}=-2$

so the winner is the answer B

hope this helps
