Think you’ve got your head wrapped around Matrices? Put your knowledge to the test. Good luck — the Stickman is counting on you!
Q. -x – 5y = 4

x + 2y = 6

Make a coefficient matrix for the above equations:

Q. If 3xy = 5 and 2x – 2y = 5 then:

Dx = 4
Dy = 4
D = 4
D = 5
None of the above
Q. What is the equation for finding y using Cramer's Rule?

y = D/Dy
y = D/Dz
y = Dy/D
y = Dx/D
y = Dz/Dy
Q. If your coefficient determinant is zero:

You have miscalculated the coefficient determinant
You won't get specific values for x and y
You know the lines represented by the equations are parallel or zero
B and C, but not A
None of the above
Q. Cramer's Rule states that:

None of the above
