I think the answer is: ACD
You are solving quadratic equations. to do so, use the quadratic formula when possible, or factor. 15- for example, you can factor (x+5)(x+3), therefore x=-5,-3. You then go back and plug in your answers to see if you can eliminate any of them.
SOLUTION:
Case: Trigonometry
Method:
Let the distance between the Sun and the Earth be 'z'
The relationship between x, y and z is:

Final answer:
In sentence,
The distance between the Sun and the Earth is the product of the distance between the Earth and the moon and the cotangent of the angle x formed using the lines from the Earth and the moon.

Good luck on your packet I just did this on mine
Answer:
Step-by-step explanation:
<u>Points given:</u>
- (-1, 3), (1, 1), (3, -1), (5, -3)
<u>Slope-intercept form:</u>
<u>Finding the slope using slope formula and the first two points:</u>
- m = (1 - 3)/(1 - (-1)) = -2 / 2 = -1
<u>Finding y-intercept using the slope and the first point:</u>
- 3 = (-1)*(-1) + b
- 3 = 1 + b
- b = 3 - 1
- b = 2
<u>So the equation is:</u>
