let D be a 2x3 matrix being = [ -2 6 4]                                                 [-1 3 h] Find h so that T(x)=Dx is onto

Suppose B and D are the following two bases for P2: B=|4x²-4x-2, ³-4x−2, 3x²-x, −3x−3] D= [−3x−3, x²+x+1» x²+1} Find the change matrix PD-B- 000 000 0 0 0 PD-B =

If A is an nxn invertible matrix, then Select one: -1 a. A= det(A)/adj(A) -1 b. A"= -1*det(A)/adj(A) -1 c. A"= -1*det(A)/adj(A)" -1 d. A = adj(A)/det(A)

Use Cramer's Rule to solve the 3 x 3 matrix A- 3B + 7Z = 13 A +B+Z = 1 A – 2B + 3Z = 4
