Answer:

The correct option is option A

A. The statement is false. Each matrix is row equivalent to one and only one reduced echelon matrix

Step-by-step explanation:

The matrix in echelon form is not in a unique form, as such row reduction can yield an infinite amount of answers. However a row reduced echelon form is unique and will give the same answer in every order that the row operation is performed

The statement is false. Each matrix has only one unique row echelon form, therefore, the correct option is option A.

Find the slope and y-intercept of the following equation: Y = ¾ x - ½

Alina [70]

Answers:

Slope = 3/4

y intercept = -1/2

================================================

Explanation:

The form y = mx+b is known as slope intercept form

m is the slope and b is the y intercept

Comparing y = (3/4)x - 1/2 to y = mx+b, we see that

m = 3/4

b = -1/2

Which of the following is the solution set of -21xl <-8

Norma-Jean [14]

Answer:

$x\:>\:4$ or $x\:$

Step-by-step explanation:

The given absolute value inequality is $-2|x|\:$

Divide both sides of the inequality by -2 and reverse the inequality sign:

$|x|\:>\:4$

By the definition of the absolute value function;

Either $x\:>\:4$ or $-x\:>\:4$

Divide through the rightmost inequality by -1 and reverse the sign.

This implies that:

$x\:>\:4$ or $x\:$
