Which of these systems of equations has no solution? Select three that apply. 14x + 7y = 30 14x + 7y = 40 17x – 10y = 38 17x –12y = 38 7x – 15y = 26 8x – 15y = 26 18x + 5y = –42 19x + 6y = –44 11x – 2y = –25 11x – 2y = –20 5x + 9y = 34 5x + 9y = 27

Step-by-step explanation:

We are given a system of equations and have to find out which do not have solution

these two are parallel lines and hence will never intersect.  So no solution

Subtracting we get y =0 and x =38/17 hence solution exist.

Subtract to get x =0 and y = -26/15.  Hence solution exist.

iv)

these two are non parallel hence intersection so solution is there.

these two are parallel lines and hence no solution

these two are parallel lines and hence no solution

you need to rotate this triangle about the origin 270 degrees clockwise to create the full square.
