Answer:
axis of symmerty = x coordinate of vertex = -b/2a
-6/2 = <u>-3 = x</u>
<u />
vertex = (-3,y)
-3^2 +6(-3)
9-18 = -9 = y
<u>(-3,-9) = vertex</u>

Answer:
There are 76 students:
g + b = 76
girls is 13 more than twice the boys:
g = 2b + 13
replace g with 2b + 13 in 1st equation
2b+13+b = 76
3b + 13 = 76
3b = 63
b = 21 boys
g = 76-21 = 55 girls

Step-by-step explanation:
The intersection point (centroid) divides the medians in ratio 2:1. it does mean that the long segment value is the short segment value multiplied by two. let's call the centroid point G.
BG=DG*2=4*2=8
CG=EG*2=2*2=4
AG=FG*2 =>FG=AG/2=6/2=3
