Answer:
Step-by-step explanation:
OK... You have to use this formula: <u>Y2 - Y1</u>
X2 - X1
- -2 represents X1
- 7 represents Y1
- 2 represents X2
- -5 represents Y2
<u>Y2 - Y1</u>
X2 - X1
<u>-5 - 7</u>
2 - - 2
<u>-12</u>
-2
Simplify by dividing both -12 & -2 by 2: <u>-6</u>
-1
It's either <u>-6</u> or it's just -6 by itself... Really sorry if I'm wrong...
-1
Subtract the second equation from double the first equation:
2x+6y-2x-(-4y)=0
10y=0
Therefore, y=0. Substituting this into the first equation, we see that:
x+3(0)=3
x=3
Therefore, x=3. The solution to this system is x=3, y=0, or (3, 0).
100 barrels * 50 liters = 5000 liters of water. 1 kiloliter = 1000 liters, so there are 5 kilo liters
