Question
Use a graphing utility to graph the inequalities.$$x^{2}-2 x y+4 y^{2}+10 x-25 \leq 0$$
Step 1
The inequality is in the form of a conic section, specifically an ellipse. The inequality sign "less than or equal to" indicates that we are looking for the set of points (x, y) that satisfy the inequality, which will be inside or on the boundary of the ellipse. Show more…
