Final answer:
To translate (5, -5) down 3 units, subtract 3 from the y-coordinate. To reflect the result over the x-axis, change the sign of the y-coordinate.
Step-by-step explanation:
To translate (5, -5) down 3 units, we subtract 3 from the y-coordinate. Therefore, the new coordinates are (5, -8).
To reflect the result over the x-axis, we change the sign of the y-coordinate. So, the final coordinates are (5, 8).
