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}\\&#10;\\ =\dfrac{x(x-1)}{x\times 1}\\&#10;\\&#10;=\dfrac{x^2-x}{x-1}

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

A set of premises and a conclusion are given. Use the valid argument forms discussed in this chapter to deduce the conclusion fr
Alex_Xolod [135]

Answer:

See deduction below

Step-by-step explanation:

I will use the known inference rules (modus ponens, etc)

From d) and b),

~r

q → r

Therefore ~q (by Modus Tollens)

From a), and our previous conclusion:

p ∨ q

~q

Therefore p (by disjunctive sillogism)

Until know, we have concluded p and ~q. By e)

~q → u ∧ s

~q  

Therefore u∧s. (Modus Ponens)

From p, u∧s, and c)

u∧s

s (simplification)

p (previous conclusion)

p∧s (adjuntion)

p∧s→t (Modus Ponens)

Therefore t, as we wanted to conclude.
