Answer: \\ {x}^{2} + 1 = 5x\Leftrightarrow {x}^{2} - 5x + 1 = 0 \\ x = \frac{ - b \pm \sqrt{ {b}^{2} - 4ac } }{2a} = \frac{5\pm \sqrt{25 - 4} }{2} = \frac{5 \pm \sqrt{21} }{2} \\ \Rightarrow A \: \& \: C

A small publishing company is planning to publish a new book. The production costs will include one-time fixed costs (such as ed
Mamont248 [21]

9514 1404 393

Answer:

   2440

Step-by-step explanation:

The difference in fixed costs is ...

  37815 -16465 = 21350

The difference in variable costs is ...

  20.50 -11.75 = 8.75 . . . . per book

Then the number of books that must be produced for the difference in variable costs to be equal to the difference in fixed costs is ...

  21350/8.75 = 2440

For production of 2440 books, the costs of the two methods will be the same.

_____

<em>Additional comment</em>

You can write expressions for total cost of each production method. When you set them equal and solve for the number of books, you find the math you end up doing is the same as that shown above.

Mel bought pizza and soda for her End of Summer party. If she spent $12.57 on the sodas and $10.95 for each pizza, how many pizz
sammy [17]

The equation that models the situation is: 89.22 = $10.95p  +  $12.57.

The cost of one pizza is $10.95. The cost of 2 pizzas would be equivalent to the multiplication of $10.95 by 2. Since we are not provided with the information on the total amount of pizza she bought, the total number of pizza bought would be represented with p.

Thus the total cost of p boxes of pizza = $10.95 x p = $10.95p

The total amount spent on sodas is $12.57.

The total amount spent is $89.22.

The equation that models the situation is: 89.22 = $10.95p  +  $12.57.

BlackZzzverrR [31]

Answer:

f(1/3) = 9

Step-by-step explanation:

f(x) = 1/x + 2/x

f(1/3) = 1/(1/3) + 2/(1/3)

f(1/3) = 1(3) + 2(3)

f(1/3) = 3 + 6

f(1/3) = 9
