Hi there!

This is definitely a start.
What am I supposed to look at?
I’m not sure I see a specific picture.
Could you tell me more about your assignment, so I can help you?
Thanks!

What is the value of x in the equation 3-2x--15x? 6 2 2 6

Wittaler [7]

Consider the given equation is $3-2x=15$ and one of the 6 in the options is -6.

Given:

The equation is

$3-2x=15$

To find:

The value of x.

Solution:

We have,

$3-2x=15$

Subtracting 3 from both sides, we get

$3-2x-3=15-3$

$-2x=12$

Divide both sides by -2.

$x=\dfrac{12}{-2}$

$x=-6$

Therefore, the value of x is -6.

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

Answer:

your answer is for sure D but I think C is also the answer

Step-by-step explanation:

Additive relationship are two quantities can be expressed as related to each other through addition. It can be written as y = x + a, where y is related to x through the addition of a constant, a. The value for a may be positive or negative.
