Which systems of equations have no solution? x + 4y = 23
-3x = 12y + 1.
2x + y = 17
-4x = 2y - 34.
2x + 4y = 22
-x = 2y - 11.
3y = 10 - x
2x + 6y = 7.
2x + y = 15.
x = 15 - 2y
y = 13 - 2x
4x - y = -1.

What are the coordinates of the point is 1/4 of the way from a (-6, -3) to b (6, 1)? a. (-3, -2) b. (0, -2) c. (-1, 0) d. (3, 2)

Two positive integers are 3 units apart on a number line. their product is 108. which equation can be used to solve for m, the greater integer? m(m – 3) = 108 m(m + 3) = 108 (m + 3)(m – 3) = 108 (m – 12)(m – 9) = 108
