Answer:

  D  (7, 0.5)

Step-by-step explanation:

The equations must be interpreted to be ...

  • y = -1/2x +4
  • y = 1/2x -3

A graph shows the solution to be (7, 0.5), matching selection D.

___

You can add the two equations together to get ...

  (y) +(y) = (-1/2x +4) + (1/2x -3)

  2y = 1 . . . . . simplify

  y = 1/2 . . . . .divide by 2

It can be convenient to use the second equation to find x.

  1/2 = 1/2x - 3

  1 = x - 6 . . . . . . multiply by 2

  7 = x . . . . . . . . . add 6

The solution is (x, y) = (7, 0.5). . . . . matches selection D.

A total of 363 were sold for the school play. They were either adult tickets or student tickets. The number of student tickets s
timurjin [86]

Answer:

The number of adult tickets sold was 121

Step-by-step explanation:

The general equation is: <em>S</em> + <em>A</em> = <em>T</em>    ;where <em>S</em> means student tickets, <em>A</em> means adult tickets and <em>T</em> means total tickets. We know that <em>S</em> is two times <em>A</em> and <em>T</em> is 363. So, <em>S</em> will be 2x and A will be x. Then, the new equation is 2x + x = 363.

<em>S</em> + <em>A</em> = <em>T</em>  

2x + x = 363  

3x = 363  

x = 363 / 3

x = 121

Adult tickets: <em>A</em> = x = 121

Student tickets: <em>S</em> = 2x = 2 * 121 = 242
