The coefficient of 6x is _____? A.6 B.x C.1
2 answers:
Answer:
Option A is correct.
6
Step-by-step explanation:
Coefficient states that a number that used to multiply the variable.
example: 4y + 2z
y and z are variables.
Coefficient of 4y = 4
Coefficient of 2z = 2
As per the statement:
To find the coefficient of 6x.
Here, x is the variable.
Then by definition we have;
Therefore, the coefficient of 6x is 6

The row echelon form of the matrix is presented as follows;
The row echelon form of a matrix has the rows consisting entirely of zeros at the bottom, and the first entry of a row that is not entirely zero is a one.
The given matrix is presented as follows;
The conditions of a matrix in the row echelon form are as follows;
- There are row having nonzero entries above the zero rows.
- The first nonzero entry in a nonzero row is a one.
- The location of the leading one in a nonzero row is to the left of the leading one in the next lower rows.
Dividing Row 1 by -3 gives:
Multiplying Row 1 by 2 and subtracting the result from Row 2 gives;
Subtracting Row 1 from Row 3 gives;
