Technical information

Behaviour being used: Adaptive mode

Minimum fraction: 0

Question summary: Given the following inverse matrices, associate them with its respective matrix. [IM1 equals # CI] , [IM2 equals # AI] , [IM3 equals # BI] {[[1,0,0],[4,1,0],[-5,-4,1]]; [[1,0,0],[4,1,0],[5,4,1]]; [[1,0,0],[-4,1,0],[5,-4,1]]} -> {IM2; IM1; IM3}

Right answer summary: [[1,0,0],[4,1,0],[-5,-4,1]] -> IM1; [[1,0,0],[4,1,0],[5,4,1]] -> IM3; [[1,0,0],[-4,1,0],[5,-4,1]] -> IM2
