Formulate the situation as a system of linear equations. Be sure
to state clearly the meaning of each variable. Solve using the
Gauss-Jordan method. State your final answer in terms of the
original question. (If the system is inconsistent, answer
INCONSISTENT. If the system is dependent, parametrize the solutions
in terms of the parameters u and v.)
A large commercial farm needs 38,000 pounds of potash, 73,000
pounds of nitrogen, and 27,000 pounds of phosphoric acid. Three
brands of fertilizer, GrowRite, MiracleMix, and GreatGreen, are
available and contain the amounts of potash, nitrogen, and
phosphoric acid per truckload listed in the table. How many
truckloads of each brand should be used to provide the required
potash, nitrogen, and phosphoric acid?
| x1 | =___________ | truckloads of GrowRite |
| x2 | = ___________ | truckloads of MiracleMix |
| x3 | = ___________ | truckloads of GreatGreen |
|
(Pounds per truckload) |
GrowRite | MiracleMix | GreatGreen |
| Potash | 400 | 600 | 700 |
| Nitrogen | 500 | 1000 | 1600 |
| Phosphoric acid | 300 | 400 | 500 |

Address the situation as a system of two equations in two
variables. Be sure to state clearly the meaning of your x-
and y-variables. Solve the system by row-reducing the
corresponding augmented matrix. State your final answer in terms of
the original question.

Hello.
Linear Algebra class.
In a linear system of equations, the solution is one of the
possibilities.
1)there is one unique solution(only one) which means the line of
the equation interest only one time at a point.
2)there are many solutions (infinity) if the lines of equations
lie on one another.
3)there is no solution if the line of the equation are
parallel.
how to test for each possibility WITHOUT
graphing the system of equations using the coefficients in each...
