Evaluate the determinant of the matrix.

• -21
• 0
• 9
• 12

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

• (-2,5)
• (-2,-5)
• (2,-5)
• (2,5)

Use Cramer's Rule to Solve.

4x + 2y = 12

4x + 8y = -24

• (5,6)

• (6,-6)

• (6,-2)

• (4,-3)

Tip: Divide both sides by -4 to isolate the cube root

• 1010

• 1000

• 990

• 90

Solve for x.

Tip: Isolate the radical by subtracting 3 from both sides.

• 5

• 4

• 41

• 82

• 4

• -4

• 2

• -2

Solve for b.

Tip: Isolate the radical by adding b to both sides.

• 9

• $y\ =\ 2$

• $None$

Find the horizontal asymptote.

• $y\ =\ \left(-2\right)$

• $None$

• $y\ =\ 0$

• $y\ =\ \frac{1}{2}$

Find the Vertical Asymptotes

• x= 0, -2
• x= 2
• x= -3, 2
