The table below represents the data for the salaries of 4 secretarial workers at a local law firm. The first row represents each employee's wage per hour, and the next 6 rows represent the amount of hours each person worked for the corresponding days of this 1 week time period. (The law firm is closed on Sundays) Use matrix multiplication to find the amount of money this law firms paid their secretaries each day of the week.
III. Used series of Elementary Row/Column Operations transform matrix given below into Row-Echelon Form (REF) or Reduced Row-Echelon Form (RREF). Fill in the blank box with the elementary operations for the given step and the corresponding result matrix. Use the word "over" without a space between the numerator and denominator to indicate the fraction bar or vinculum. Also, for the interchange symbol, write the word "interchange" with no spaces between the rows to be exchanged. For example, R2 is written as R2-2R1 R1 is written as (4over3)R1; -R2 is written as (-(1 over2)) R2; and R2-2R1 or -2R1+R2; and R2 R1 is written as R2interchangeR1. 3 [2 8 4 17) 2 14 5 1 5 10 -1 1.
