<h3>What is the row echelon form of a matrix?</h3>
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;
Adding Row 2 to Row 3 gives;
Dividing Row 2 by -2, and Row 3 by 18 gives;
The above matrix is in the row echelon form

Answer: -8
Step-by-step explanation: because the formula is mx+b=y and the -8 is the b
First what you wanna do is get y by it’s self. To do that is to first add 5 on each side.
-5+3y=-4
+5 +5
3y= 1
Than you divide 3 on each side and it would give you y=1/3 if it’s a fractions problem but if you looking for decimals you would have to divide 1 by 3 which gets you .33333333.
Hello!
Since the lines on are not dotted then the symbols have to be less than or equal to / greater than or equal to
If y was greater than or equal to x then we would have a line that goes through point (0, 0) and has the region above it shaded
This is what happens in the picture so we know that the answer is C
The answer is C
Hope this helps!
Total spoon required is mentioned in the Attachment.
Step-by-step explanation:
- Clustered column bar graph used.
- each 18 milligrams divide by the data provided
- beef is blue label
- plant is orange labelled.
- Microsoft office used Iron,Calcium and Vitamins in column
- Microsoft office used Beef in one row.
- Microsoft office Plant used in 2nd row.
- Chart title, Axis title and design changed.
- Bar graph is better interpretation for three columns.
