passes through (5,-2), perpendicular to the graph of x + 2y = 8
Solve each system of equations. Check each answer algebraically.
11. -6x + 3y = 33
-4x + y = 16
12. 2y = 5x – 1
x + y = -1
13. x + y + z = -1
2x + 4y + z = 1
x + 2y – 3z = -3
Graph each system of inequalities. Name the coordinates of the
vertices of the feasible region. Find the maximum and minimum
values of the given function.
14. 52y2-3
4x + y s5
-2x + y s5
f(x, y) = 4x – 3y
15. x>-10
12y? -6
3x + 4y = -8
2y 2 X – 10
