Select three ratios that are equivalent to 16: 12. Choose 3 answers:
A-8:6
B-32:24
C-4:3
D-12:8
E-24:16

The answer is A, B and C

Step-by-step explanation:

A is equivalent because the ratio has been halved

B is equivalent because the ratio has been doubled

C is equivalent because the ratio has been divided by 4

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.
