Use the given matrix to find the expression. 8 8 Formulate the situation as a system of linear equations. Be sure to state clearly the meaning of each variable. Solve B = w w 4 -B 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, parametrizations in terms of the parameters u and v.) A large commercial farm needs 43,500 pounds of potash, 83,500 pounds of nitrogen, and 31,000 pounds of -B = 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?
