Which of the following is the quotient of the rational expressions shown here? x/x-1 / 1/x 1.

WINSTONCH [101]

The quotient of the rational expressions is $\rm \dfrac{x^2-x}{x-1}$ .

<h3>Given that</h3>

Rational Expression; $\rm \dfrac{x}{x-1}$ ÷ $\rm \dfrac{1}{x+1}$

<h3>We have to determine</h3>

Which of the following is the quotient of the rational expressions shown here?

<h3>According to the question</h3>

Rational Expression; $\rm \dfrac{x}{x-1}$ ÷ $\rm \dfrac{1}{x+1}$

Then,

The quotient of the rational expressions is,

$\rm \dfrac{x}{x-1}$ ÷ $\rm \dfrac{1}{x+1}$

$\rm =\dfrac{x}{x-1} \times \dfrac{x+1}{1}\\
\\ =\dfrac{x(x-1)}{x\times 1}\\
\\
=\dfrac{x^2-x}{x-1}$

Hence, The quotient of the rational expressions is $\rm \dfrac{x^2-x}{x-1}$ .

Evaluate : 5-3(x-1) when x=7

Andrei [34K]

Answer:

<h3> $\boxed{ \bold{ \boxed{ \sf{ - 13}}}}$ </h3>

Step-by-step explanation:

Given , x = 7

let's find :

$\sf{5 - 3(x - 1)}$

Plug the value of x

⇒ $\sf{5 - 3(7 - 1)}$

Subtract 1 from 7

⇒ $\sf{5 - 3 \times 6}$

Multiply the numbers

⇒ $\sf{5 - 18}$

Calculate

⇒ $\sf{ - 13}$

Hope I helped!

Best regards!!
