Answer:
Step-by-step explanation:
- First, lets get rid of the fraction. I did this by multiplying both sides by .
- We want to isolate on one side of this equation. Let's put any values with on one side of the equation, and normal integers on the other.
- Divide both sides by .
- If your teacher wants you to leave your final answer as an improper fraction, your final answer is this. If they want it to be a mixed number or decimal, your final answer will be:
The ordinate is the y element in an ordered pair in a Cartesian coordinate system. The quadrants in which the ordinates are positive should be at quadrants I and II. Therefore, the correct answer from the choices listed above is option A.

Answer: D) Angle 6 and angle 16</h3>
==================================================
Explanation:
We have four lines that form 4 intersection points. Let's label these points A,B,C, and D. Check out the diagram below.
We can say that angle 1 is a corresponding angle to angle 9 because
- a) The two angles are in the same position of their four corner configuration (both are in the north of each four corner configuration)
- b) the angles mentioned are at points that are adjacent to one another. Point A is adjacent to point D
Similarly, angles 4 and 12 are corresponding as well. They are both in the east quadrant and point A is adjacent to point B. A similar thing happens with angles 5 and 7.
In contrast, angles 6 and 16 are not corresponding angles. Yes they are both in the south quadrants of their four corner configuration, but point A is not adjacent to point C. Angle 6 corresponds to only angle 14 and angle 8, but not angle 16.
To find X:
-b/2a=-2/2(-2)=.5
plug in .5 to the equation to find y.
-2(.5)²+2(.5)+1
=1.5
Vertex: (.5,1.5)
