Suppose x is sold, $280 each , and y is the total financial cost. The first equation in the system is then certainly y = 280x.
The vertex form <span>y-k = a(x-h)^2 where (h,k) is the vertex, and y is the y-intercept.
So, plug the values in.
</span><span>11,000-24,000 = a(0-500)^2
-13,000=250,000a
a=-0.052
y-</span><span>24,000 = -0.052(x-500)^2
y= </span><span>-0.052(x-500)^2 + 24,000
This is the second equation in the system.
The answer is then A, which contain the system </span><span>of equations which can be used to determine must be sold for the company to make a profit.</span>
Answer:
(A) 
Step-by-step explanation:
Slope intercept form of equation of line is 
The standard form of equation is 
Now let 
substituting the value of A and B in slope intercept form,
Answer:
r + c ≤12
r > 3
c > 2
Step-by-step explanation:
Jennifer is putting together a selection of flowers that has at most 12 flowers in it.
r = number of roses she uses
c = the number of carnations
At also means Less than or equal to.
It is represented by ≤
She is choosing either roses or carnations. She wants to pick at least three roses
r > 3
and at least two carnations.
= c > 2
Therefore, the system of inequality that represents this scenario is written as:
r + c ≤ 12
r > 3
c > 2
