Write the augmented matrix of the system of equations given below. (10 points)
1 answer:
The augmented matrix of the system of equations is
The system of equations is given as:
-2x + 2y - z = 13
-3x - y + z = 7
-x + 3y - 2z = 0
Remove the variables x, y and z
-2 2 -1 13
-3 -1 1 7
-1 3 -2 0
Express as matrix
Hence, the augmented matrix of the system of equations is

Answer:
simple interest is 8350 for 15 months
Step-by-step explanation:
<u>Explanation</u>:-
The simple interest formula A = P (1 + r t)
where 'P' is the principal amount of money to be invested at an interest Rate' r % per period for' t ' number of time periods.
Given data The principal P is borrowed at a simple interest rate r for a period of time t.
Given principal amount P = $8000
simple interest rate r = 3.5%
period of time 't' = 15 months
<u>Calculation</u>:-
Putting time into years
t = 1.25 years
r = 3.5%
r = 0.035 per year
now equation is A = P (1 + r t)
A = 8000 ( 1+ ( 0.035 X 1.25)
A = 8000 X 1.04375
A = 8350
simple interest is 8350 for 15 months.
