Answer:
The median is 56
Step-by-step explanation:
50, 52, 52, 55, 56, 56, 56, 58, 58, 59, 60
Then you start eliminating
1. 52, 52, 55, 56, 56, 56, 58, 58, 59
2.52, 55, 56, 56, 56, 58, 58
3. 55, 56, 56, 56, 58
4. 56, 56, 56
5. 56
6. So, the median is 56.

Given:
The equation of a quadratic function is:
To find:
The equation of the axis of symmetry for the given function.
Solution:
If a quadratic function is , then the equation of the axis of symmetry is:
...(i)
We have,
Here, . So, the equation of axis of symmetry by using (i), is
Therefore, the correct option is C.
The first answer is that the system represents 2 lines. They are two parallel lines.
For the second question, it just represents 1 line. In this case, the two lines are right on top of each other. This is because they are the same equation, just in different forms.
