Answer:
Dependent Variable- l Independent Variable-b
Step-by-step explanation:
Dependent Variables are always Y and Independent Variables are always x.
In this case y=I and x=b. The amount of water your water bottle will hold will never change. But the amount of water you drink can change.
It is positive.
Hope this helped.
The row echelon form of the matrix is presented as follows;
<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

It seems like you have the answer already. but heres how its calculated.
so the missing number is 20 **cross multiply 100 and 3 to get 300 then divide 15 into 300 to get 20**
so the missing number is 50
**cross multiply 100 and 80 to get 8000 then divide 160<span> into 8000 to get 50**</span>
