Solving Systems using MatricesVersion en ligne This activity will assess your understanding of solving systems of equations by using matrices on a TI-84 Calculator. Make sure to have a calculator or use the Wabbit Emu app on your computer par Tianny Sims 1 This video is going to solve a system of equations. 3x-2y=2 and 2x-y=2. Watch carefully and write the buttons that were pressed a ok b what?!?!?!?! 2 What buttons were just pressed and in what order? a 2nd Mode b 2nd x^-1 c 2nd + d 2nd GRAPH 3 What are the dimensions of matrix A a 2x2 b 2x1 c 1x2 d 2nd GRAPH 4 What numbers make up the matrix a variables b coefficients c constants d 2nd GRAPH 5 What are the dimensions of matrix B a 1x2 b 2x2 c 2x1 d 2nd GRAPH 6 What buttons were just pressed a 2nd + b 2nd x^-1 c 2nd Mode d 2nd GRAPH 7 What is the value of x and y a x=2, y=2 b x=a, y=b c x=21, y=22 d 2nd GRAPH 8 Write down this system and solve it using the method you just learned. 2x-1y=4 and 3x + 2y = 13 a x=2, y=2 b x=3, y=3 c x=1, y=2 d x=3, y=2
