The first question is 1.5
We get that by dividing the amount of coco (6) but the number of cups (4)
The second answer is 4/6 or .666666
We get that but dividing 4 by 6
To solve the two sets of equations simultaneously, subtract one equation from the other to obtain
3x^5 + 2x^2 - 10x + 4 - (4x^4 + 6x^3 - 11) = 0
3x^5 - 4x^4 - 6x^3 + 2x^2 - 10x - 7 = 0
This is a polynomial of degree 5 to be solved for zeros.
A graphing calculator will yield 3 real zeros (verifiable by Descartes Rule of Signs).
Graph 2 should be right because it moves up 1 because of the +1 that is in the parentheses.
