Determine if these matrices are inverses by calculating AB: matrix 1matrix 2 matrix 3 c11 = c12 = c21 = c22 = So the matrices inverses of one another.

his chances of getting a coin of higher value is 4/19

step-by-step explanation:

b. 153 students do not participate in sports and seventy-five 12th graders were surveyed

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
