[10 points] Forward elimination changes Ax = b to the system Rx = d. If the process of elim- ination subtracted 2 times row 1 from row 2 and then 4 times row 1 from row 3, what matrix connects R and d to the original A and b? (That is, find E such that R = EA and Eb = d).

Write the system of equations represented by the matrix. 0 1 2 4 -2 3 6 9 1 0 1 3

Someone answer asap for ! michele pushes a box d meters across a floor. she uses a force f, in newtons, to push the box. she pushes the box for t seconds. the formula p = fd/t calculates the power, p, in watts, that it takes for michele to complete the task. solve the formula for d.
