Answer: F (cos(230)).
Explanation:
Cosine corresponds to the x coordinate of points on a circle when the radius is drawn in like this, so the answer would be the cos of that angle, but you have to account for the fact that the 50 degree angle marked is just the reference angle not the entire angle so you have to add 180 degrees to that to get 230.
For this, I'll be using the substitution method. Since y = 1/3x - 6, replace the y variable in the first equation with 1/3x - 6 and solve for x:

Now that we have the value of x, plug it into either equation to solve for y:

<h3><u>In short, the solution to this equation is (3,-5).</u></h3>
Answer:
49
Step-by-step explanation:
To complete the square we use the formula:

So we can plug in 14 for b to find c.

Now this equation can be factored into:
