Well there are no choices listed so it's going to be hard to say which; we'll write an expression for all of them and then give a few instances.
A parabola with a minimum forms a CUP, concave-up positive, meaning the coefficient a on x² must be positive, a>0.
The general form with vertex (p,q) is
y = a(x-p)² + q
So for us, all our parabolas are of the form
y = a(x- -3)² + 9
y = a(x² + 6x + 9) + 9
y = ax² + 6ax + 9(a+1)
That's the general form for a parabola with vertex (-3,9); a>0 assure the parabola has a minimum at the vertex.
Some instances:
a=1 gives
Answer: y = x²+6x+18
a=4 gives
y = 4x² + 24x + 45
Other positive <em>a</em>s give other possible answers; without the choices it's impossible to know which one they're seeking.
Answer:
3 cups of water
Step-by-step explanation:
it she is making the humming bird stuff and 1/4 is supposed to be sugar and she uses a cup of sugar then the other stuff is supposed to be water so 3 cups of water
Answer:
73
Step-by-step explanation:
First, to get rid of the square root, square both sides of the equation to get:
y-9=64
Then, move 9 to the other side to get
y=73
Do 9+4 because you need to get m alone. you get 13 plug 13 in for m (13-4=9) and then 9=9
