Prove that if x is irrational, then 1/x is irrational

ozzi

Proof by contradiction.

Let assume that when $x$ is an irrational number, then $\dfrac{1}{x}$ is a rational number.

If $\dfrac{1}{x}$ is a rational number, then it can be expressed as a fraction $\dfrac{a}{b}$ where $a,b\in\mathbb{Z}$ .

$\dfrac{1}{x}=\dfrac{a}{b} \Rightarrow x=\dfrac{b}{a}$

Since $a,b\in\mathbb{Z}$ , the number $x=\dfrac{b}{a}$ is also a rational number. But this contardicts our initial assumption that $x$ is an irrational number. Therefore $\dfrac{1}{x}$ must be an irrational number.

Solve for x: 2x – y = (3/4)x + 6

vovangra [49]

Answer:

B.

Step-by-step explanation:

2x – y = (3/4)x + 6

2x - (3/4)x = y + 6

(8x -3x)/4 = y + 6

5x/4 = y + 6

5x = 4(y + 6)

5x = 4y + 24

x = (4y + 24)/5

x = 4(y + 6)/5
