Math Problem Statement
I have the following matrix: first row -35 35 23 -165, second row 33 -32 -20 163, third row 18 -18 -12 84, fourth -73 75 53 -320. Show the matrix in rref form, I don't need to see steps, just the result as I am checking if my solution was correct.
Solution
The given matrix in reduced row echelon form (RREF) is:
1 & 0 & 0 & 0 \\ 0 & 1 & 0 & 0 \\ 0 & 0 & 1 & 0 \\ 0 & 0 & 0 & 1 \end{pmatrix}$$ Let me know if you need any further clarification or have additional questions! Here are some related questions you might find useful: 1. How do you convert a matrix into RREF form using row operations? 2. What are the properties of a matrix in reduced row echelon form (RREF)? 3. How do you determine the rank of a matrix from its RREF? 4. Can a matrix be in RREF but still not be invertible? 5. How do you solve a system of linear equations using the RREF of a matrix? **Tip:** RREF is useful for solving systems of equations, as each row corresponds to an equation, with the variables clearly isolated.Ask a new question for Free
