Which values for A and B will create infinitely many solutions for this system of equations?

Ax-y=8

2x+y=B

A = 2.B - 8

A=-2.B=8

A = 2.B=-8

A--2.8--8

Use the graph to determine the range. which notations accurately represent the range? check all that apply. (–∞, 2) u (2, ∞) (–∞, –2) u (–2, ∞) {y|y ∈ r, y ≠ –2} {y|y ∈ r, y ≠ 2} y < 2 or y > 2 y < –2 or y > –2
