Question

What is the value of the rational expression 6-x\x+5 when x=2

Answer 1

6-2/2+5= 4/7=.57142857142 but usually you just keep it as a fraction so 4/7 is the answer

Answer 2

Answer:  The required value of the given rational expression at x =2 is $\dfrac{4}{7}.$

Step-by-step explanation:  We are given to find the value of the following rational expression when x = 2 :

$E=\dfrac{6-x}{x+5}~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)$

To find the required, we need to substitute x = 2 in the expression (i).

So, from (i), we have

$E_{x=2}=\dfrac{6-2}{2+5}=\dfrac{4}{7}.$

Thus, the required value of the given rational expression at x =2 is $\dfrac{4}{7}.$
