3). y = -1/3x + 5
4). y = -1x +5
Slope intercept form: y = mx + b
m = slope
b = y intercept
This makes sense to me: m=(y-6)/3
m is the number of muffins each friend gets, y is the original quantity of muffins, -6 is = to the number of muffins you freeze, and the /3 is to split the remaining (unfrozen) muffins equally.
Answer:
You distribute the 2xy and get
2xy(3xy + 5y - xy^2) = 6(x^2)(y^2) + 10xy^2 - 2(x^2)(y^3)
You first need to change the percent into a decimal then multiply by 80 to get your answer
.35*80=28
