Answer:
(-1,8)
Step-by-step explanation:
Look at the top point of the parabola type thing. I know that it's not a parabola, but IDRK how else to describe it. If you see the top point at one of the answers, it is most likely correct.
Volume of Cuboid = l x b x h
9000 mL = 30 x 15 x h
h = 9000/30 x 15
h = 20cm
That amount, which I assume you're asking about, is a 4 degree drop in temperature each week.
The y-intercept is (0,7) and the x-intercept is (-2,0).
