Answer:  A. There were 500 liters in the tank when the leak started, and it is  decreasing by 9 liters per minute.

Step-by-step explanation:

This equation is in the form; y =mx + c.

<em>c</em> in this equation is the value of y when x is at 0.

<em>c</em> in the above formula is 500 which means that the number of litres (y) at zero minutes(x) is 500 litres.

<em>m</em> is the rate of change as a result of a change in x.

<em>m</em> in this equation is -9 which means that the water is reducing by 9 litres every minute (x).

How do I solve this?

Answer:

  • x = 10
  • y = 19

Step-by-step explanation:

Consecutive interior angles between parallel lines are supplementary.

Let's start with x.

  (8x +40)° +(6x)° = 180°

  14x +40 = 180 . . . . . . . . . divide by °, collect terms

  14x = 140 . . . . . . . . . subtract 40

  x = 10 . . . . . . . . divide by 14

__

We can use the same approach for y:

  (7y)° +(3y -10)° = 180°

  10y = 190 . . . . . . . . . . . divide by °, add 10, collect terms

  y = 19 . . . . . . . . . . . divide by 10
