= 3 Determine the value of h such that the matrix is the augmented matrix of a consistent linear system. 미 4 -7 14

Which of the following statements are true? Remember that a mathematical statement is said to be true if it is always true, under all circumstances. VA. The solution set of a linear system whose augmented matrix is aj az az | 6 is the same as the solution set of Ах — b, if A — [ај ар аз |- V B. A vector b is a linear combination of the columns of a matrix A if and only if the equation Ax = b has at least one solution. VC. If A is an m × n matrix and if the equation Ax = b is inconsistent for some b in R", then A cannot have a pivot in every row. D. The equation Ax = b is referred to as a vector equation. VE. If the augmented matrix A | b] has a pivot position in every row, then the equation Ax = b is inconsistent. O F. The first entry in the product Ax is a sum of products.
