Answer:
This shows 3 pivot position matrixes.
Step-by-step explanation:
The given matrix is:
The option D is correct for this matrix.
The matrix is invertible and the given matrix has 3 pivot positions.
The matrix is invertible if its determinant is nonzero.
Multiply the 3rd row by 1/3.we get:
Now, add the first row with third row:
Replace third row by first row:
This shows 3 pivot position matrixes.
Hence, a matrix is invertible and has 3 pivot positions.
Answer:
<u>the order in which the ratio is drawn should be the same as listed.</u>
Explanation:
What this means is that since a ratio compares the sizes of two numbers (eg 4:2 or 4 ratios 2 or ), it would be wrong to change the order of a ratio when drawn in a diagram.
For example, changing the order to (2:4 or 2 ratios 4), which then because not
. Hence, it is important to remember that diagram of the ratio of two or more quantities should be the same as listed.
