1. Write an augmented matrix for the following system of equations.-3x+9=75x-6y=12. Write an augmented matrix for the following system of equations.7x-2y+7z=-48x-4y+z=-2 y-z=-23. Write the system of equations associated with the following augmented matrix. (Type equations using x and y as the variables.)1 0 | 50 1 | 64. Use the Gauss-Jordan method to solve the following system of equations.x+y=85xx+4y=355. Use the Gauss-Jordan method to solve the following system of equations.6x-5y=712x-10y=16. Use the Gauss-Jordan method to solve the following system of equations.4x-5y=716x-20y=287. Use the Gauss-Jordan method to solve the each system of equations.4x+4y-4z=42x-y+z=5x-4y+3z=-88. Use the Gauss-Jordan method to solve the each system of equations.3x+8y-z=05x-y+3z=18x+7y+2z=19. Use the Gauss-Jordan method to solve the each system of equations.7x-3y+3z=57x+2y-z=1235x-10y+11z=3210. If 30 lb of rice and 20 lb of potatoes cost $18.20, and 20 lb of rice and 12 lb of potatoes cost $11.52, how much will 10 lb of rice and 50 lb of potatoes cost? Let x be the cost of 1 lb of rice and y be the cost of 1 lb of potatoes. Set up two linear equations from the given information using x and y as the variables.11. A person has$34,000invested in stock A and stock B. Stock A currently sells for$20a share and stock B sells for$70a share. If stock Btriplesin value and stock A goes up 50%, his stock will be worth$93,000.How many shares of each stock does he own? The person owns ? shares of stock A snd ? shares of stock B?
