Solve using Gauss-Jordan elimination. 1) 9x - y - 9z = 9 6x + 4y + 5z = 92 -6x - 5y + z = -77 A) (6, 4, 9) Labor Materials SHORT ANSWER. Write the word or phrase that best completes each statement or answers the question. Find the system of equations to model the problem. DO NOT SOLVE THIS SYSTEM. 2) Labor and material costs for manufacturing each of three types of products M, N, and P are 2) given in the table: M = M $50 $60 [2 0 1] Store 1 3 3 0 Store 2 B) (6, 9,4) Product N $40 $40 The weekly allocation for labor is $50,000 and for materials is $80,000. There are to be 3 times as many units of product M manufactured as units of product P. How many of each type of product would be manufactured each week to use exactly each of the weekly allocations? Set up a system of linear equations, letting x1, x2, and x3 be the number of units of products M, N, and P, respectively, manufactured in one week. Provide an appropriate response. C) (-6, 9, 12) Solve the problem. 3) 3) A retail company offers, through two different stores in a city, three models, A, B, and C, of a particular brand of camping stove. The inventory of each model on hand in each store is summarized in matrix M. Wholesale (W) and retail (R) prices of each model are summarized in matrix M. Find the product M N and label its columns and rows appropriately. What is the wholesale value of the inventory in Store 1?
