Answer:
The correct answer is, Option d.
Explanation:
It is given a system of equation.
- 2x - 2y + 5z = 1
- 5x - 5y + 7z = 4
9x - 2y + 2z = -1
To find the augmented matrix
To find the augmented matrix we have to write the coefficients of the given system of equation.
- 2 - 2 5 | 1
- 5 - 5 7 | 4
9 - 2 2 | 1
Therefore the correct answer is Option d.
