Solve the following system of equations using reduced row echelon form you may use the calculator for the rref but you need to show how to set up the system and the matrix and intepret the answer. if there is no solution, explain how you know. 3x,+2x,-5x,+2x,= 4 xx -1 x-3x,+4x,-6 2x, +3x,+3x-1 x+x-2x,-3 +2x,-x,2 b) a) 2x+4x,+x-3x,=-2 x-4x,-7x,-x,=-19

Solve the following pair of equations for x and y: ax/b_ by /a= a +b; ax - by = 2ab

Data for the height of a model rocket launch in the air over time are shown in the table. darryl predicted that the height of the rocket at 8 seconds would be about 93 meters. did darryl make a good prediction? yes, the data are best modeled by a quadratic function. the value of the function at 8 seconds is about 93 meters. yes, the data are best modeled by a linear function. the first differences are constant, so about 93 meters at 8 seconds is reasonable. no, the data are exponential. a better prediction is 150 meters. no, the data are best modeled by a cubic function. a better prediction is 100 meters.
