Linear Inequalities: Estimations
Multiple linear inequalities with two unknowns
The two lines given by the equations #-30\cdot x+33\cdot y-585=0# and #-40\cdot x-43\cdot y-355=0# divide the plane into four areas, indicated in the figure below as I, II, III and IV.
Which area is the solution of the following inequalities?
\[-30\cdot x+33\cdot y-585\gt0, \quad -40\cdot x-43\cdot y-355\gt0 \]
Which area is the solution of the following inequalities?
