Question: In Problems 1-4, use the method of Lagrange multipliers to solve these problems from section 12.8 1. ((x, y) = 10 + x + y;

In Problems 1-4, use the method of Lagrange multipliers to solve these problems from section 12.8
1. ((x, y) = 10 + x + y; S = {(x, y): x2 + y2 ( 1}
2. ((x, y) = x + y - xy; S = {(x, y): x2 + y2 ( 9}
3. ((x, y) = x2 + y2 + 3x - xy;
4. S = {(x, y): x2 + y2 ( 9}
