Question

Determing the values of h such that the matrix is the augmented matrix of a consistent linear system

Select the correct choice below and, if necessary, fill in the answer box to complete your choice

A) Matrix is an augmented matrix of a consistant linear system if h= ?

B) Matrix is an augmented matrix of a consistant linear system if h doesnt equal ?

C) The matrix is an augmented matrix of a consistant linear system for every value of h

D) The matrix is not the augmented matrix of a consistant linear system for any value of h

Explanation / Answer

This is the intersection of two lines, so to be consistent the slopes must be different,

8/-2 and 24/-6 must not be the same as h/-1, hence h should not be equal to 4

ie the determinant of the coefficient matrix cannot be 0

A) Matrix is an augmented matrix of a consistant linear system if h= 4
