9. Describe in your own words how you can tell whether an equation has an infinite number of solutions or no solution at all.
10. Solve:
10x+2(x-6)=3(4x-4)
11. Solve:
2(9x-6)=6(3x-2)+2
12. Solve:
8+4x=2x+8+2x

∆abc is reflected across the x-axis and translated 2 units up to give the image ∆a'b'c' with coordinates a'(1, 1), b'(2, -1), c'(2, 1). what are the coordinates of the preimage ∆abc? a. a(-1, 1), b(-2, 3), c(-2, 1) b. a(1, 1), b(2, 3), c(2, 1) c. a(1, -3), b(2, -1), c(2, -3) d. a(1, -3), b(2, -5), c(2, -3)
