Write the system of equations that corresponds to the augmented matrix.  

Use a TI calculator to solve the following system. (hint: use the RREF function also known as the “cheat” method). All answers should be whole numbers. Make sure you only enter the number (no decimals).    6x + z = -26  w + x + 5y – z = 266w + y + 5z = 13  w + x + 3y = 14 Enter values here:  w= , x=, y=, z=

A company makes 3 types of cable. Cable A requires 3 black, 3 white, and 2 red wires. B requires 1 black, 2 white, and 1 red wire. C requires 2 black, 1 white, and 2 red wire. They used 120 black, 110 white and 100 red wires. How many of each cable were made? Setup the system of equations to solve this problem by selecting the coefficients and constants for each colored wires. Black Wires:     A+B+C=White Wires:    A+B+C=Red Wires:       A+B+C=

Find the equilibrium point for the given demand and supply functions. Here p represents price and q represents quantity.p = -1.7q + 15 (demand)p = 0.7q + 3 (supply) Find the equilibrum quantity (q). units (Round to nearest whole number) Find the equilibrium price (p). $ (Do not enter the $ sign. Round to nearest cent.)

A ceramics workshop makes serving bowls, platters, and bread baskets to sell at its Winter Festival. A serving bowl takes 3 hours to prepare, 2 hours to paint, and  10 hours to fire. A platter takes  15 hours to prepare, 3 hours to paint, and 4 hours to fire. A bread basket takes 4 hours to prepare,  15 hours to paint, and 7 hours to fire. If the workshop has  104 hours for prep time,  59 hours for painting, and  108 hours for firing, how many of each can be made? Let x represent the number of serving bowls, y represent the number of platters and z represent the number of bread baskets. Select the system of equations that best fit the problem.
