Solve for each inequality. 8 ≤ x - (-14) 31 ≥ b - (-18) -5 < n + (-1)

Gennadij [26K]

Answer:

$8 \leqslant x - ( - 14) \\ 8 \leqslant x + 14 \\ 8 - 14 \leqslant x + 14 - 14 \\ - 6 \leqslant x \\ x \geqslant - 6$

___o__o__

$31 \geqslant b - ( - 18) \\ 31 \geqslant b + 18 \\ 31 - 18 \geqslant b + 18 - 18 \\ 13 \geqslant b \\ b \leqslant 13$

__o__o__

$- 5 < n + ( - 1) \\ - 5 < n - 1 \\ - 5 + 1 < n - 1 + 1 \\ \\ - 4 < n \\ n > - 4$

Show that 2 - sqrt(2) is irrational

babunello [35]

Answer:

This proof can be done by contradiction.

Let us assume that 2 - √2 is rational number.

So, by the definition of rational number, we can write it as

$2 -\sqrt{2} = \dfrac{a}{b}$

where a & b are any integer.

⇒ $\sqrt{2} = 2 - \dfrac{a}{b}$

Since, a and b are integers $2 - \dfrac{a}{b}$ is also rational.

and therefore √2 is rational number.

This contradicts the fact that √2 is irrational number.

Hence our assumption that 2 - √2 is rational number is false.

Therefore, 2 - √2 is irrational number.
