In quadrant III, cosine is <u>negative</u>

In quadrant III, sine is <u>negative</u>

x^2+y^2 = 1 represents the unit circle. This is a circle centered at the origin with radius 1. The point (x,y) is on the unit circle where x = cos(theta) and y = sin(theta)

If theta is between 180 and 270 degrees, then

x = cos(theta) leads to -1 < x < 0, ie x is some negative number between -1 and 0

y = sin(theta) leads to -1 < y < 0, so y has similar properties to x above.

Because we don't know what value theta is exactly, we can only comment on the fact that each result is positive or negative.

The four quadrants are set up where quadrant 1 is in the upper right corner. Then you move counter-clockwise to sweep through the other quadrants 2 through 4.

Marianna [84]
<span>A function is said to be an odd Function is the graph of the function is symmetric with respect to the origin. A function is odd if and only if f(–x) = –f(x).

The transformations that describe the graph of an odd function includes:

1.) </span><span>180° rotation around the origin

2.) </span><span>reflection over the line y = x</span>

1. Solve the inequality.
Sauron [17]

Answer:

Your final answer is either

x≥-2   if your initial inequality was

6x+2≤2(5-x)

OR

x≤-2

if your initial inequality was

6x+2≥2(x-2)

Step-by-step explanation:

As shown you have an equality, not an inequality.

-6x+2=2(5-x)          distribute through parenthesis

-6x+2=2(5)+2(-x)

-6x+2=10-2x           add 2x to both sides

2x-6x+2=10-2x+2x

-4x+2=10                subtract 2 from both sides

-4x+2-2=10-2

-4x=8                      divide both sides by -4

-4x/(-4) = 8/(-4)

x = -2

With the ≥ or ≤ sign you would solve the exact same way

except for the point where when dividing both sides by

-4 requires you to reverse the inequality.

Your final answer is either

x≥-2   if your initial inequality was

6x+2≤2(5-x)

OR

x≤-2

if your initial inequality was

6x+2≥2(x-2)
