The answer is (0, 1). By plugging in it, both equations would be correct. However, you could also use elimination to solve these problems.

Total profit P is the difference between total revenue R and total cost C. Given the following total-revenue and total-cost fu

gavmur [86]

Answer:

The profit function is:

$P(x)=-x^2+1280x-3300$

The maximum value is 406, 300 occurring when x = 640.

Step-by-step explanation:

The revenue function is:

$R(x)=1300x-x^2$

And the cost function is:

$C(x)=3300+20x$

Then the total profit function will be:

$P(x)=R(x)-C(x)=(1300x-x^2)-(3300+20x)=-x^2+1280x-3300$

This is a quadratic function.

Therefore, the maximum value of the total profit will occur at its vertex point.

The vertex of a quadratic is given by:

$\displaystyle \Big(-\frac{b}{2a}, f\Big(-\frac{b}{2a}\Big)\Big)$

In this case, a = -1, b = 1280, and c = -3300.

Then the point at which the maximum profit occurs is at:

$\displaystyle x=-\frac{1280}{2(-1)}=640$

And the maximum profit will be:

$P(640)=-(640)^2+1280(640)-3300=406300$

Answer:

210

Step-by-step explanation:

210 students attend the school. if 60 students are taking art, and there are 2 art students in every 7 students, that means there are 30 groups of 7 because 30×2=60 so since the other 5 do not take art, you would multiply 30×5 and get 150. Then you would add 60 and you would get 210

Kevin had to make 14 visits to the dentists last year to take care of his braces. Each visit cost #124. How much did the visits

VMariaS [17]

Answer:

Step-by-step explanation:

Let's look at simpler cases. If there was just one visit that would be 124. if there were two, each time he'd have to pay 124 so it's 124+124 = 248. So this is multiplication, because next would be three, which is 124+124+124 or 124 time 3.

In total then it's 124*14. You may usually use an x for multiplication, and if you do just keep in mind * can also be used. or, if something is inside of parenthesis like this 124(14) or (124)14. If you need help doing the multiplication let me know.
