G(x)=X+11 where y is the total temperature after it rose & x is the temperature when Iko woke up. F(x)= g(x) -14 . Where f(x) is the temperature after it dropped 14 and g(x) is the temperature it was by lunch time.
To calculate the slope you need to do (y2-y1)/(x2-x1). So you would get:
(17-12)/(4-9)
5/-5
=-1
Hope this helps.
Each dimension has to be 1" or bigger, otherwise the cube won't fit. _________ WAIT ! The container doesn't have to be rectangular, and that opens up a lot more possibilities. The smallest possible rectangular container is a little tiny cardboard cube whose dimensions are all 1", just like the contents. But you could also keep it in a container shaped like a pyramid, a cylinder, an egg, etc. If the container is a sphere, then its radius has to be at least 0.866 inch.
Combine like terms so you end up with 10x+2y
