Find the determinant of the matrix .

• A

• B

• C

• D

Determine if the matrix has an inverse, if so find it.

• No

• 0 1

  -1 2

• -1 3

  1 -2

• Does not have an inverse

Graph the system of inequalities. Name the coordinates of the vertices of the feasible region. Find the maximum and minimum values of the function for this region.
3 ≤ y ≤ 6
y ≤ 3x + 12
y ≤ -2x + 6
f(x , y) = 4x - 2y

• The maximum value is 0 at (0, 6). The minimum value is - 20 at (-3, 3).
• The maximum value is 0 at (-3, 3). The minimum value is - 20 at (0, 6).
• The maximum value is 0 at (-2, 6). The minimum value is - 20 at (1.5, 3).
• The maximum value is 0 at (1.5, 3). The minimum value is - 20 at (-2, 6).
