Answer:

B.

Step-by-Step equation:

We have:

-3x-y=3

3x-9y=-2

And so for any given

x, say x = 0, we're going to have different

y values. In this case, the first equation gives

y=−1, and the second gives

y= -2/9

In short, we have 2 parallel lines

Perpendicular lines, C is the answer.

To solve this equation, Simplify the first and then the second.

First will be solved like: -y=3x+3, y=-3x-3. The second will be simplified as: 9y=3x+2, y=1/3x+2/9. Then you divide by 3.t.

Please help me with circle questions below
IRINA_888 [86]

For first question, What is approximate value of "......" this part is missing so please write whose approximate value question is asking to find

For second question we have to find tan\Theta

In right triangle ABC as show in attachment,

tan\Theta = \frac{opposite side}{adjacent side} = \frac{AB}{BC}----(1)

Now AB is given by distance of point A from x axis which will be given by its y - coordinate. So AB = \frac{1}{2}

Similarly BC is the distance of point A from y axis (horizontal distance ) and that will be given by x coordinate of A. So BC = \frac{\sqrt{3}}{2}

Plug these values in equation (1)

tan\Theta = \frac{AB}{BC} = \frac{\frac{1}{2}}{\frac{\sqrt{3}}{2}}

To divide fractions we flip (reciprocal ) bottom fraction and multiply it to top fraction as shown

tan\Theta = \frac{1}{2} \times \frac{2}{\sqrt{3}}

Now 2 in top and bottom cancels out so we are left with

tan\Theta = \frac{1}{\sqrt{3}}

so thats the final answer for tan\Theta
