Matrix Row Transformations Quiz

What is the first step in solving systems of linear equations using matrix row transformations?

• Add the rows together

• Convert all entries to decimals

• Write the augmented form of the matrix

• Subtract the rows from each other

How do you transform the first entry of a row into a one?

• Add the row to itself

• Subtract the row from itself

• Divide by two

• Multiply by the reciprocal

Why is it recommended to use fractions instead of decimals in matrix transformations?

• Fractions are easier to multiply

• Decimals are not allowed in matrices

• Decimals are harder to add

• Fractions provide more accuracy

What is the goal when transforming the second column of a matrix?

• Convert all entries to fractions

• Make the last entry a one

• Make the first entry a one and the rest zeros

• Make all entries zero
