Answer:
Step-by-step explanation:
We can do this a couple of ways. We can graph it -- see below. Or we can do the math.
Math
y = x^2 - 2x - 15
This trinomial factors into
y = (x - 5)(x + 3)
from which
x - 5= 0
x = 5
and
x + 3 = 0
x = - 3
The y intercept is the value obtained when all the xs on the right = 0
y = 0^2 - 2*0 - 15
y = - 15

The graph is below.
Answer:
10 cents
Step-by-step explanation:
In order to answer this question we have to find how much each chicken strip costs individually.
Let's start with the 4 piece.
To find how much each piece costs we have to divide $2.40 by 4. Like this:
In the 4 piece, every chicken strip costs .60 cents.
Now, let's do the 6 piece.
Like before we are going to divide $3.00 by 6.
In the 6 piece, every chicken strip costs .50 cents.
Therefore, customers save 10 cents when they buy the larger quantity.
