CAN SOMEONE HELP WITH THIS PLS AND TY

I agree because for every 2 girls there are 1.25 boys

Step-by-step explanation:

10 divided by 5  is 2 and 8 divided by 5 is 1.25

Because for every 2 girls there are 1.25 boys sooo...

yes I agree because when also 1 boy enter there will already be another 2 new girls joining.

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this
