Y= a(x-2)(x+4) the graph of the equation in the xy- plane is a parabola with vertex (c, d) which of the following is equal to d? a) -9ab) -8a c) -5ad)-2acan you tell me how to solve it.

A

Step-by-step explanation:

First set y=0, then solve resulting in y=2,-4, plug those values into the midpoint formula. then you get x=-1, then plug -1 in for x in the equation. so it becomes y=a(-1-2)(-1+4). Solve that and you get y=a(-3)(3), multiply that together and you get -9a

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!
