Question

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

Answer 1

Answer: The required value of the given rational expression at x =2 is
`(4)/(7).`

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

`E=(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)=(6-2)/(2+5)=(4)/(7).`

Thus, the required value of the given rational expression at x =2 is
`(4)/(7).`

Answer 2

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