Answer:

x + y ≤ 600
5x +7y ≥ 3500
it is possible

Step-by-step explanation:

a) We can write two inequalities, one for the number of tickets, and one for the necessary revenue.

x + y ≤ 600 . . . . . . . limit imposed by available seating

5x +7y ≥ 3500 . . . . required revenue to meet expenses

b) For x = 330, the first inequality puts one limit on y:

330 +y ≤ 600

y ≤ 270

And the second inequality puts another limit on y:

5(330) +7y ≥ 3500

7y ≥ 1850 . . . . subtract 1650

y ≥ 264.3 . . . . divide by 7

The number of tickets that must be sold to meet expenses is 265, which is less than the number that can be sold, 270. It is possible to meet expenses.

You can use the definition for the vertex form of a quadratic equation and then can can do conversion of that quadratic equation in that form.

The correct vertex form of the given equation is given by

Option C: $h(x) = (x-5)^2 - 18$

<h3>What is vertex form of a quadratic equation?</h3>

If a quadratic equation is written in the form

$y = a(x-h)^2 + k$

then it is called to be in vertex form. It is called so because when you plot this equation's graph, you will see vertex point(peak point) is on (h,k)

This point is called the vertex of the parabola that quadratic equation represents.

<h3>How to convert the given equation to vertex form?</h3>

We first take out coefficient of x squared, and then inside the bracket, we try to make perfect square like situation.

The given equation is $h(x) = 7 + 10x + x^2\\$

Converting it in vertex form, we get:

$h(x) = 7 + 10x + x^2\\\\\\h(x) = x^2 + 10x + 7\\h(x) = x^2 + 10x + 25 -25 + 7\\h(x) = (x+5)^2 - 18 \text{\: (Note how the form} \: a^2 + b^2 + 2ab = (a+b)^2 \:\rm got\: made)$

Thus, we have h = -5 and k = -18

The plot of the given equation is attached below.

Thus,

The correct vertex form of the given equation is given by

Option C: $h(x) = (x-5)^2 - 18$

If a stadium has 15,000 seats sold at $10.00, $12.50, and $15.00 equally distributed in three sections, how much can be made if

MissTica

First we have to determine how many people fir in each section.
Since these sections are evenly distributed, each section has a third of the capacity, thus= 15,000/3 = 5000 persons per section.

Now we determine revenue by section by multiplying times the ticket price.

5,000 * $10.00 = $50,000
5,000 * $12.50 = $62,500
5,000 * $15.00 = $75,000

We add up the totals for $187,500 and that's the answer!
