1 and 2 are two seperate problems but please answer both 1. What payment must I invest at the end of each quarter into an account paying 2.3%/year interest compounded quarterly, if I will need $10,000 in five years? 2. Solve using the modified Gauss-Jordan method 2x+3y + 5z = 2 . 4x + y - z=4 2x + y = 3
(8 pts) 1. What payment must I invest at the end of each quarter into an account paying 2.3%/year interest compounded quarterly, if I will need $10,000 in five years?
(9 pts) 2. Solve using the modified Gauss-Jordan method, as presented in class 2x+3y + 5z = 2. 4x + y - 2=4 2x + y
pls show clear working (15) 8. If $12,000 is invested in an account paying 3.75% compounded quarterly, how much money will be in the account at the end of 10 years? (20) 9. a. 3x-2y =12 Solve 1 x-3y=11 by either the ADDITION/ELIMINATION or SUBSTITUTION method. Solve the same system using matrices (Gauss-Jordan Elimination is the fancy term!). b. (2x+2y = 2 (15) 10. Solvex+ y+z=1 by any method you choose. Clearly indicate your method and your solution. 3x +...

Solve by using the Gauss-Jordan elimination method: x+y-z=2 2x+3y-z=7 3x-2y+z=9 I know that you have to convert them to 1 0 0 | 2 0 1 0 | 7 0 0 1 | 9 I am just not clear on how to do this row by row. Any help would be greatly appreciated.
