Determinants and Cramer's Rule

Find the value of the determinant for the following matrix:

• -151

• -105

• -137

• NONE

Find the value of the determinant.

• -169

• 19

• 67

• -153

Solve using Cramer's Rule:
x - 3y - 5z = 7
-y - 4z = 11
-3x - y + 3z = 5

• (1, -5, -3)

• (-5, 1, -3)

• (2, 0, 3)

• (0, 2, 3)

Solve the system using Cramer's Rule.  5x + 8y = -12
3x + 5y = -7

• (1, -10)

• (-4, 7)

• (-4, 1)

• (1, 10)

Use Cramer's Rule to Solve the Following:
2x - 5z = 6
-3x + 4y - 2z = 26
-3x + y - 4z = 18

• (-6, 5, -3)

• (5, -6, 4)

• (5, -6, -3)

• (-2, 4, -2)

Use Cramer's Rule to solve the following:
-3x + y = 4
-5x + 2y - 4z = -3
-x - 4y - 6z = 11

• (2, -5, -3)

• (2, -4, -4)

• (2, -3, -5)

• (-3, -5, 2)

Solve for x and y using CRAMER'S RULE
3x + 2y = 16
7x + y = 19

• (-2,5)

• (-2,-5)

• (2,-5)

• (2,5)

Solve for x and y.  Use Cramer's
2x − 3y = −1
 y = x − 1

• (-2,-3)

• (0,-1)

• (3,4)

• (4,3)

Solve for x and y using Cramer's Rule
3x + 2y = 16
7x + y = 19

• (-2,5)

• (-2,-5)

• (2,-5)

• (2,5)

Solve using Cramer's Rule

• (-5,-6)

• (-6,3)

• (-5,0)
