Linear Algebra
Find the best approximation to z by vectors of the form
c1v1 + c2v2
z = [3, -5, 2, 3], v1 = [3, -1, 0, 1], v2
= [1, 2, 2, -1]
The best approximation to z is (Simplify
your answer.)

Linear Algebra Problem:
Show that if x and y are vectors in R2, then x+y and
x-y are the two diagonals of the parallelogram whose sides are x
and y.
Thank you

Solve the system.
x+y+z=1
x+y-2z=3
2x+y+z=2

A) Write another way of modeling the max flow as a linear
program by defining variables for each s-t path. What is an
interpretation of this
LP?
B) What is the dual of the above LP? What is an
interpretation of the LP?
This shows that there may be multiple LP formulations of a
problem

his is a linear algebra problem
Determine the values of a for which the system has no
solutions, exactly one solution, or infinitely many solutions.
x + 2y - 2z = 3
3x - y + 2z = 3
5x + 3y + (a^2 - 11)z = a + 6
For a = there is no solution.
For a = there are infinitely many solutions.
For a ≠ ± the system has exactly one solution.

Solve the system.
y'1 = y1 + 12 y2
y'2 = 2y1 + 12y2
what is y1 and y 2 ?
I Don't need the answer rather i need to know how to use Octave
or mathlab function/formulas to compute the value.
I know there are eig() etc

in what way the flow capacity of an arc limits (has an impact
on) a maximal flow problem? It would be easier to solve such a
problem if the flow capacities are large numbers?

Explain how the maximum flow problem can be cast as a linear
programming problem...
