Use Cramer's rule to solve the system of equations. If D = 0, use another method to determine the solution set.2x + 8y + 8z = 24x + 4y + 4z = -4x + y + z = -6
A. Cramer's rule does not apply since D = 0; ?
B. {(-6, -1, 5)}
C. {(-1, 5, -6)}
D. Cramer's rule does not apply since D = 0; {(2z-1, z + 2, z)}

Solve. Assume the exercise describes a linear relationship. When writing a linear equation, write the equation in slope-intercept form.A faucet is used to add water to a large bottle that already contained some water. After it has been filling for 5 seconds, the gauge on the bottle indicates that it contains 17 ounces of water. After it has been filling for 11 seconds, the gauge indicates the bottle contains 35 ounces of water. Let y be the amount of water in the bottle x seconds after the faucet was turned on. Write a linear equation that models the amount of water in the bottle in terms of x.
A. y = 
x + 
B. y = 3x + 2
C. y = 3x + 24
D. y = -3x + 32
