Answer:
The price per serving is $0.315, therefore, it's less than $0.5
Step-by-step explanation:
In order to calculate the price per serving, we can first calculate the price per cup, this is done by dividing the total value of the box by the number of cups it can serve:

Since each serving is
of a cup, then it's price has the same proportion and is given by:

The price per serving is $0.315, therefore, it's less than $0.5
We have
Parabola
with vertex (0,0) and focus (0,-4)
we know that
is a vertical parabola that opens down
the standard form of the equation is of the form
(x-h)²=-4p(y-k)
where
(h,k) is the vertex----------> (0,0)
p is the distance from the vertex to the focus or directrix
in this problem
p=4
(x-h)²=-4p(y-k)------> x²=-16y-------> y=-(1/16)x²

Answer:
I think the answer is 7.5
Step-by-step explanation:
The y is the same for both equations. Equate them
-x - 5 = 2x + 4 Add x to both sides
- 5 = 3x + 4 Subtract 4 from both sides.
- 9 = 3x Divide by 3
x = -9 / 3
x = - 3
y = - x - 5
y = -(-3) - 5
y = - 2
So that point is where the two equations meet.
