(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 = 3
(9 pts) 2. Solve using the modified Gauss-Jordan method, as presented in class 2x+3y + 5z = 2. 4x + y - 2=4 2x + y
(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?
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.
pls show clear working
