Answer:
Step-by-step explanation:
If you plot the vertex and the point, you see that the point is above the vertex. Therefore, this is a positive parabola with the work form of

We have values for x, y, h, and k. Let's write the equation of the parabola, put it into function notation, then find another x value at which to evaluate it.
and
and
8 = 9a - 1 and
9 = 9a so
a = 1. The equation of the parabola in function notation is

Since the vertex is at (3, -1) it would make sense to evaluate the function at x values close to the vertex. Let's evaluate the function at an x value of 4:
and
and
f(4) = 0. That means that another point on this parabola will be (4, 0).
Answer: 15120
Step-by-step explanation:
Given: The number of players at point guard = 10
The number of players at shooting guard = 12
The number of players at small forward = 7
The number of players at power forward = 2
The number of players at center = 9
Then, the number of different teams William could draft is given by :-
10∗12∗7∗2∗9=15120
Hence, William could draft 15120 different teams.
Answer:
Option B is correct.
The reflection rule is followed here is,
.
Explanation:
Since, the triangle is reflected over the x-axis , then only y- coordinates will get changed but the x coordinates will remain the same.



Therefore, the only reflection rule on the coordinate plane that verifies the triangle are congruent when reflected over x-axis is, 
The sum is the number zero
