Answer:

The value of rational expression at x=5 is -2

Step-by-step explanation:

Given: [tex]\dfrac{15-x}{x-10}[/tex]

We are given rational expression and need to find the value of expression at given value of x=5

So, we will put x=5 into the rational expression

[tex]\Rightarrow \dfrac{15-x}{x-10}[/tex]

[tex]\Rightarrow \dfrac{15-5}{5-10}[/tex]

Simplify numerator and denominator

[tex]\Rightarrow \dfrac{10}{-5}[/tex]

[tex]\Rightarrow -2[/tex]

Hence, The value of rational expression at x=5 is -2

Answer:

The value of given rational expression is -2 when x = 5.

Step-by-step explanation:

We are given the following information in the question:

The value of x is 5.

We have to find the value of rational expression:

[tex]\displaystyle\frac{15-x}{x-10}[/tex]

Putting x = 5 in the above expression we have:

[tex]\displaystyle\frac{15-x}{x-10} = \frac{15-5}{5-10} = \frac{10}{-5} = -2[/tex]

Thus, the value of given rational expression is -2 when x = 5.
