I am asking for assistance with the below questions: 1. Explain why vectors QR and RQ are not equivalent. 2. Explain in your own words when the elimination method for solving a system of equations is preferable to the substitution method. I have attempted to answer the questions but am wishing to see if done correctly

Show that the system of equations 2x + y + z = -6a 2x + y + (b +1)z = 4 bx + 3y + 2z = 2a Has a unique solution except when b = 0 and b = 6. If b = 0, show that there is only one value for a for which a solution exists, and find the general solution in this case. Discuss the case when b = 6. Interpret your so
(See attached file for full problem description) I am looking for a response similar to the BrainMass example mathematics response, which clearly explained how the answer was found.
I would like to know if I am on the right track to writin this as a "systems of equations" using the substitution process. How much further do I have to go if this is right so far? A family made an investment for 1 year that earned $7.50 simple interest. If the principal had been $25 more and the interest rate 1% less, the in
Using Cramer' rule, solve the linear system 3x + 2y = 4 12x + 6y = 6

Let Y1 = theta + epsilon1 Y2 = 2*theta + xi + epsilon2 Y3 = theta - 2*xi + epsilon3 where E(epsilon(i)) = 0. Find the least squares estimates of theta and xi. See attached file for a cleaner version of the problem.
Question One The relationship between the load on a reel, L kilonewtons per metre (L kNm 1) and the reel diameter, x metres, is modeled by a graph consisting of two parabolic arcs, AR and BC, as shown. Arc AR is part of the parabola L =px2 + qx +r Points D(0. 1, 2.025), E(0.2, 2.9) and F(0.3, 3.425) lie on arc AR. Setup a syst
Solve the linear system. Indiciate if the system is inconsistent, dependent, or neither. 3x + 2y + z = 2 4x - y + 3z = -16 x + 3y - z = 12 keywords: 3, x, y, z
Solve the equation. Determine whether it is inconsistent, dependent, or neither. 3x - 2y = 0 9x - 8y = 7
Solve the linear system. State whether the system is inconsistent, dependent, or neither. x/6 + y/3 = 8 x/4 + y/2 = 12
If a system of nonlinear equations contains one equation whose graph is a circle and another equation whose graph is a line, can the system have exactly one solution? If so, what does the graph of the situation look like?
The following is a non-linear system. Solve it 1/x + 2/y = 3 2/x + 1/y = 4 (Hint: Try a change in variable. Let u = 1/x ; let v = 1/y)
Exercise. IV. This problem is a partial investigation of which n×n matrices over C have cube roots; that is, for which n × n matrices A over C there is an n × n B over C such that A = B3. Since C is algebraically closed, every n × n matrix over C is similar over C to a matrix in Jordan canonical form. A. Suppose that A

Three functions e^x, sinx and cosx are given. They must be shown linear independent by using Wronskian.
I have another question on linear approximation using e. Suppose I want to approximate e^ 0.9. I am assuming that I let f(x) equal the following e^ 0.9 ~ e^0.5 + e^0.5 (0.9-0.5) = 0.4e^0.5 Am I on the right track?
