Answer:  \textsf{x}^2\textsf{ - 14x + 24}

-------------------------------------------------------------------------------------------------------------

Given:  \textsf{x = 12 and x = 2}

Find: \textsf{Determine the quadratic equation}

Solution:  In order to determine the quadratic equation we need to move the integers onto the side where x is and then distribute.

<u>Move the integers</u>

  • Solution #1
  • \textsf{x - 12 = 12 - 12}
  • \textsf{x - 12 = 0}

  • Solution #2
  • \textsf{x - 2 = 2 - 2}
  • \textsf{x - 2 = 0}

<u>Create and expression and distribute</u>

  • \textsf{(x - 12)(x - 2) = 0}
  • \textsf{(x * x) + (x * -2) + (-12 * x) + (-12 * -2) = 0}
  • \textsf{x}^2\textsf{ - 2x - 12x + 24 = 0}
  • \textsf{x}^2\textsf{ - 14x + 24 = 0}

Therefore, after completing the steps we were able to determine that the quadratic equation that will have solutions of x = 12 and x = 2 is x^2 - 14x + 24.

Tickets for a dance recital cost $15 for adults and $7 for children. The dance company sold 253 tickets, and the total receipts
elixir [45]

Answer:

Adult tickets =125

Child tickets = 128

Step-by-step explanation:

Let the number of adult and children tickets sold be x and y respectively

So that

x+y= 253--------1

Since total sales/receipt is $2,771

And given that tickets for a dance recital cost $15 for adults and $7 for children hence

15x+7y= 2771-------2

Solving equation 1 and 2 simultaneously we have

x+y= 253---------------1

15x+7y= 2771----------2

Let us multiply equation 1 by 15 to get equation 3 to eliminate x and subtract equation 2 from 3

15x+15y=3795---------3

-{15x+7y= 2771----------2

0+8y=1024

8y= 1024

y= 1024/8

y= 128 tickets

So solve for x let us put y= 128 in equation 1

x+ 128=253

x=253-128

x= 125 tickets
