The row-echelon form of the augmented matrix of a system is given. find the solution of the system.

[1 0 -1 3]
[0 1 5 -4]
[0 0 1 1]

probability for j is 1/4

while

a is 1/6

step-by-step explanation:

at each of the parallel lines adjacent angles are supplementary. the angles have special names identifying their positions with respect to the parallel lines and transversal. they are corresponding angles, alternate interior angles, or alternate exterior angles. an angles is congruent to its matched angle.

step-by-step explanation:

a = (-2, 0)

b= (-4, 0)

c = (-5,2)

d = (-1,2)

-3.5 is the distance.

i've had this question so choose the one in the absolute value sign.
