Consider the following three simultaneous equations and the planes they describe in the space of (*1, $2, X3 ) coordinates. -321 + 2 - 03 = 1, -$1 - 302 + 203 = 1. Which of the following statements is true? Select one: O a. This is an inconsistent system; there is no solution for { $1 , 22, 23}. O b. The three planes intersect along a line. O c. The system defines a unique solution for {x1 , 12, 73}. O d. The three planes do not intersect at all.Let A be a matrix with LU decomposition, where 3 0 0] 1 2 -1 L= 1 2 0 and U = 0 1 3 -1 0 3 0 0 1 3 Solve Ax = b for x, when b = 3 C1 = 12 = C3 =
