Here is a simple example of what I am trying to do; fill the area described by the three inequalities:
$$ y \le 11 + x \label{1} \tag{1}$$ $$ y \le 27 - x \tag{2}$$ $$ y \le \frac{1}{5}(90 - 2x) \tag{3}$$
I have so far:
Plot[{11 + x, 27 - x, 1/5 (90 - 2 x)}, {x, 0, 20},
Filling -> {2 -> {{3}, {White, LightBlue}}}]
Which produces:
My question is how to add multiple constraints on an area in general -- so for this specific question add the constraint specified by equation $\eqref{1}$.
Region
and then useRegionPlot
to plot it, including a colored fill. Search this website for similar questions. $\endgroup$
