Answer:5x-20y=12
Step-by-step explanation:
The function in vertex form is

(refer to your other post I solved it there).
The general form of quadratic equations in vertex form is

, where (h, k) is the vertex of the parabola.
Here, a = 1, h = -6 and k = -54
Therefore, the vertex is (-6, -54) and it is a maximum because a = 1 is postive.
33/50 because it is biggest
The number is (2√3) / 3
To find the missing number, convert what it says in words to an equation:

Divide both sides by 15:

Take the square root:
