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

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
