Consider the following linear systemx1 + 2x2 ∈ x3 + 5x4 = 12x1 + 2x2 ∈ 2x3 + 6x4 = 3x1 + x2 ∈ x3 + 3x4 = 2(a) Row reduce the augmented matrix to the reduced row echelon form.(b) Determine if the linear system is consistent or inconsistent. (If the systemis consistent, you do not need to find the general solution.)

Sample response: if the graph passes the horizontaline test, then the function is one to one. functions that are one to one have inverses that a therefore, the inverse is a hinction compare your response to the sample response above. what did you include in your explanation? a reference to the horizontal-line test d a statement that the function is one-to-one the conclusion that the inverse is a function done
