If x is 6, then 7x= a. 13 b. 42 c. 42x d. 76

Jeremy wants to determine the number of solutions for the equation below without actually solving the equation. which method should jeremy use?

The image of abc is a'b'c. what transformations would result in this image? abc is reflected over the line x = 1, then is rotated -90° around the origin. abc is reflected over the line y = x - 1, then t: (x, y) → (x - 1, y - 1). abc is rotated 90° around the origin, then is reflected over the y-axis. abc is rotated -90° around the origin, then is reflected over the line y = -1.
