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.
Answer:
Q1 1000 1
3500 3.5
500 .5
75 .075
1 .001
x 1/1000x or .001x Q2 Y= 1/1000x
Step-by-step explanation:
just search up 1000 meters to 1 kilometer and go from there :)
Answer:
x=-7/3 and y=-6
Step-by-step explanation:
6x-3(3x+1)=4
6x-9x-3=4
-3x-3=4
-3x=7
x=-7/3
y=3(-7/3)+1
y=-6
None of these because they all are 0
