Solve the system of equations by finding the reduced row-echelon form of the augmented matrix for the system of equations. 3x-4y-5z=-27 5x+2y-2z=11 5x-4y+4z=-7 a.(1,5,51) b.(10,5,51) c.(10,51,23) d.(1,5,2)

D. (1, 5, 2)

Step-by-step explanation:

It is convenient to let a graphing calculator do this. See the attachment.

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

1. minimum

2. 6400

3. eight

hope this !
