The general or standard form of a parabola is
(y-k) = a(x+h)^2
h,k are the intersection points of parabola
Intersection points are where y= 0, or x=0
itsnorigin at (,0,0)that means h=0, k=0
it passes through points (-1,2) and (1,2)
So then
y= ax^2 , 2 = a (-1)^2
this means a= 2
Then results standard form equation
Y = 2• X^2
Answer:
27
Step-by-step explanation:
17 - 8 = 9 people came
The number of presents brought is 3×9 = 27.
Jackie got 27 presents.
I only know D. but I'll try to figure out the rest too. D. 9 years old
Associative property of multiplication means that it doesn't matter where the parentheses are placed because it will still be the same answer.
So your answer would be 1, 4 x (3 x 6) = (4 x 3) x 6
I hope this helps!
