Complete the statements.

Answer:

1. 30

2. 150

Step-by-step explanation:

$3tan^2(x)-1 =0$

Lets assume tan(x) = u

$3u^2(x)-1 =0$

Now we solve for 'u'

add 1 on both sides

$3u^2(x) =1$ , divide both sides by 3

$u^2 = \frac{1}{3}$

Take square root on both sides

$u = +-\frac{1}{\sqrt{3} }$

We replace tan(x) for 'u'

$tan(x) = +-\frac{1}{\sqrt{3} }$

x = 30 because $tan(30) =+\frac{1}{\sqrt{3} }$ in first quadrant

x = 30 (tan is positive in first quadrant)

$tan(x) =-\frac{1}{\sqrt{3} }$

x = 150 because $tan(150) =-\frac{1}{\sqrt{3} }$ in second quadrant

tan is negative in second quadrant

2y-18x=-26 solve for y

Alekssandra [29.7K]

2y - 18x = -26

Add 18x to both sides.

2y = -26 + 18x

Divide by 2 on both sides.

y = -13 + 9x

y = 9x - 13

Brandon bought a new pair of shorts at the store when they were having a 10% off sale. If the regular price of the pair of short

spayn [35]

You would multiply the orignial price by (10%) converted to decimal to find the discount:
21 * 0.10
=2.10

Then, you subract the discount from the original price to see how much he paid:

21 - 2.10 = $18.90
