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: True, because if a number is a whole number, for instance, it must also be an integer and a rational.

Answer: 800 miles
Step-by-step explanation: His budget is $120
He then spends $40 for the week
So that is $80 that he has left
Each mile is only $0.10, so you divide $80 by $0.10
After dividing you get 800
That means that he can drive for 800 miles and still stay within his budget
