Find a and that solve the vector equation: a) 2 13 a (²) + ² (¹) = (₂2) ß 29 Suppose the above equation is expressed as Ax = b with x = the coeffieints of the equations in one matrix form as (Ab)= Rows: 2 Columns: 3 (8). . Express

c) For the 2x2 matrix C, find C-¹ by hand using C-1 = decadjC, where adj is the adjoint operator. 34 0 = [³4] 5 7

Let a₁ = 12 - [ 4 ] → - [ ¹2 ], and b - [44] = = a₂ -12 48 Is b a linear combination of a₁ and a₂? OA. b is not a linear combination. B. Yes b is a linear combination. C. We cannot tell if b is a linear combination. Either fill in the coefficients of the vector equation, or enter "NONE" if no solution is possible. a₁ + b = 8₂
