Answer:

(4, 18)

Step-by-step explanation:

We can just pluck the x values into the equation: y = 5x -1 to see if the y values fit.

1. y = 5(4) - 1

= 20 - 1

= 19 (Nope, 18 is not 19)

2. y = 5(3) - 1

= 15 - 1

= 14 (Yep, same as option)

3. y = 5(0) - 1

= 0-1

= -1 (Yep, same as option)

4. y = 5(2) - 1

= 10 - 1

= 9 (Yep, same as option)

Answer:

The answer is cot(x)

Step-by-step explanation:

<h3>Greetings !</h3>

$\tan(x) \csc {}^{2} (x) - \tan(x)$

Rewrite using trig identity

$- \tan(x) + \csc {}^{2} (x) \tan(x)$

use the Pythagorean idea

$\csc {}^{2} (x) = 1 + \cot {}^{2} (x)$

$- \tan(x) + (1 + \cot {}^{2} (x)) \tan(x)$

simplify

$\cot {}^{2} (x) \tan(x)$

use basic trigonometric identity

$\tan(x ) = \frac{1}{ \cot(x) }$

simplify

$\cot {}^{2} (x) \frac{1}{ \cot(x) }$

gives you

$\cot(x)$

Hope it helps!
