Answer:
The reduced row-echelon form of the linear system is
Step-by-step explanation:
We will solve the original system of linear equations by performing a sequence of the following elementary row operations on the augmented matrix:
- Interchange two rows
- Multiply one row by a nonzero number
- Add a multiple of one row to a different row
To find the reduced row-echelon form of this augmented matrix
You need to follow these steps:
- Divide row 1 by 2
- Subtract row 1 from row 2
- Subtract row 1 multiplied by 5 from row 3
- Subtract row 2 multiplied by 3 from row 1
- Subtract row 2 multiplied by 3 from row 3
- Multiply row 2 by 2
- Divide row 3 by −19
- Subtract row 3 multiplied by 16 from row 1
- Add row 3 multiplied by 6 to row 2
Answer:
martina is 22 feet below sea level
Step-by-step explanation:
Marina goes down 20 feet
then rises 7 feet which is 20 - 7 = 13
then goes down 9 more feet which is 13 + 9 = 22 feet
20 - 7 + 9 =22
Martina is 22 feet below sea level.

Step-by-step explanation:
In mathematics, the complex conjugate of a complex number is the number with an equal real part and an imaginary part equal in magnitude but opposite in sign. For example, the complex conjugate of 3 + 4i is 3 − 4i. In polar form, the conjugate of is.
