Question 250004: Factor 3z^2+14z +8 I have tried this repeatedly and I keep coming up with an answer that is exactly like the problem Found 2 solutions by richwmiller, Edwin McCravy:
You can put this solution on YOUR website! . Use the technique developed in this section to solve the minimization problem. Minimize C = x − 6y + z subject to x − 2y + 3z ≤ 10 2x + y − 2z ≤ 15 2x + y + 3z ≤ 20 x ≥ 0, y ≥ 0, z ≥ 0 The minimum is C = at (x, y, z) = ~~~~~~~~~~~~~~~~~~~~~ I don't know which technique was developed in this unknown to me section, which you do ...
Question 937871: If x + 2y + 3z = 6, 2x + 3y + z = 8 and 3x + y + 2z = 10, what is the value of x + y + z? Answer by TimothyLamb (4379) (Show Source):
You can put this solution on YOUR website! Use the simplex method to maximize P = 5x + 4y + 3z subject to the constraints: x ≧ 0, y ≧ 0, z ≧ 0, x + y + z ≦ 30, 2x + y + 3z ≦ 60, 3x + 2y + 4z ≦ 84 You can ignore the three x ≧ 0, y ≧ 0, z ≧ 0, because the process itself keeps the variables non-negative. Put the constraint inequalities, first the objective function equation ay ...

You can put this solution on YOUR website! the average of 2x + y + 3z is equal to (2x + 3y + z) / 6 there are 6 elements in all. 2 * x 1 * y 3 * z so, if you break them up, you get x + x + y + z + z + z. that's 6 elements. take the sum and divide by 6 and you get the average. an example would be as follows: x = 7 y = 6 z = 5 2 * x = 2 * 7 = 14 1 * y = 1 * 6 = 6 3 * z = 3 * 5 = 15 the sum is 30 ...
You can put this solution on YOUR website! find the value of k so that the system of the equation x + y + 3z = 0 4x + 3y + kz = 0 2x + y + 2z = 0 has non-trival solution This is called a homogeneous system. It has only zeros on the right side. The trivial solution for all homogeneous systems is (x,y,z) = (0,0,0). But many homogeneous systems have other, non-trivial solutions. Make the ...
You can put this solution on YOUR website! Simplify the following expression. 2x - 2y + 5z - 2x - y + 3z Combine like terms: 2x - 2x = 0 -2y - y = -3y 5z + 3z = 8z Now we have: -3y + 8z Answer: 8z - 3y Lennox Obuong Algebra Tutor Nairobi, Kenya Email: obuong3@ 379708.555win5win.com
x - 2y + 3z = 11 2x - z = 3 3y + z = -8 The 2nd equation is the simplest and it already has y eliminated in it. so let's eliminate y also from the 1st and 3rd, so we'll have two equations with y eliminated in them: To eliminate y from the 1st and 3rd equations, x - 2y + 3z = 11 3y + z = -8 we multiply the top one by 3 and the bottom one by 2
