Select all equations that have no solution. 6 + 18x = 12 + 27x-9x
4x - 6 - 2x = 2x - 7
20x -- (10x + 2) = 10x + 7
8 + 21x - 7x = 8 + 14x

PLEASE HURRY!! :(

Need match the functions with correct transformation. f(x) = -3x f(x) = |x-1|+3 f(x) = √(x+3) 1/2x² f(x) = (x+1)²-3 4|x| 1. compress by a factor of 1/2 2. stretch by a factor of 4 3. shift to the left 3 4. shift to the left 1 5. shift up 3 6. reflection
