Answer #1

Use Scilab to solve the following set of nonlinear algebraic
equations: x^3y -4y^2 +3x = 1 and 6y^2 - 9xy= 5 with initial
guesses of x = 2, y = 2.

2.Use separation of variables to solve (3x^2(1-y^2))/2y with
initial condition y(1)=2.
3.State the solution of the homogeneous ODE with roots of its
characteristic equation of r= 1,1,1,+-7i,3+-5i.
4.Consider the system of linear equations:

x+2y-z=-1
5x+7y-4z=9
solve this system using: a) Carmer's rule, b)Gauss-Jordan
elimination, c) an inverse matrix.

Solve the system of linear equations. If the system has an
infinite number of solutions, set w = t and solve for x, y, and z
in terms of t.)
x + y + z + w = 6
2x+3y - w=6
-3x +4y +z + 2w= -1
x + 2y - z + w = 0
x, y, z, w=?

Solve for the general solution

b. (4, 1)
c. This system is dependent
d. No solution
e. None of these

Solve this system of equations.
4x + 3y + z = -4
x - 3y + 2z = -25
11x - 2y +3z = -63
Write the solution as an ordered triple.
PLEASE MAKE SURE THIS IS CORRECT. I KEEP PAYING FOR THE WRONG
ANSWERS.

Solve the following system of equations using matrices(row
operations). If the system has no solution, say that it is
inconsistent.
x + 6y+ 3z = 1
3x - 3y + 3z = 3
4x + 3y + 4z = 4
