Construct an augmented matrix for this linear system:

x − y − 4z = 5
2x + 2z = 0
4x + y + z = 3

Step-by-step explanation:

In an augmented matrix, each row represents one equation in the system and each column represents coefficients (including signs) of variables or the constant terms.

So, the first row is

the second row is

and the third row is

Hence, an augmented matrix for this linear system is

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.

what is the answer?
