Which of the following points is a solution of y ≤ -|x| - 1?A. (0, 5)B. (1, 7)C. (7, 1)

1 answer:

3 0

I would reccomend plugging in each coordinate.

A. (0,5)
5 ≤ -|0| - 1
 $5 \neq -1$
FALSE

B.(1,7)
7 ≤ -|1| - 1
$7 \neq -2$
FALSE

C. (7,1)
1 ≤ -|7| - 1
$1 \neq =-8$

None of these check, if there is an option D feel free to post it in the comments.

Answer:

$\displaystyle x = 2 \sqrt{3}$

Step-by-step explanation:

we would like to solve the following equation:

$\displaystyle \sqrt{3} = \frac{6}{x}$

in order to do so do cross multiplication:

$\displaystyle x \sqrt{3} = 6$

divide both sides by √3:

$\displaystyle x = \frac{6}{ \sqrt{3}}$

since we ended up with a square root on the denominator so we can consider rationalising the denominator to do so multiply both numerator and denominator by √3 which yields:

$\displaystyle x = \frac{6}{ \sqrt{3}} \times \frac{ \sqrt{3} }{ \sqrt{ 3} }$
