The correct answer is A. It satisfies the top equation but not the bottom equation.
This can be found by plugging in the given x and y values to the system, as seen in the attached picture.
I hope this helps! :)
Get y by it self and then graph it. Should be y=5x+4
Answer:x=-8

Think of it as two rectangular prisms next to each other, and find the volume of each one separately.
The big one on the left has a volume of 4 * 12 * 6, or 288.
The smaller one on the right has a volume of 2 * 6 * 6, or 72.
288 + 72 = 360. 360 cubic feet of water are needed.
