Veronica performs a dilation on figure A. She uses a scale factor of 3 with a center of dilation at the origin. She says the coordinates of the image of point X are (3, 12). What mistake may Veronica have made, and what are the correct coordinates of the image?

She have added 3 to the x coordinate, instead of multiplying by 3. The correct coordinates are (0, 12)

She multiplied only the x-coordinate by 3; the correct coordinates are (9, 4).

She multiplied both coordinates by 3; the correct coordinates are (9, 36).

She did not multiply both coordinates by 3; the correct coordinates are (3x, 3y).

△ABC is rotated 90° clockwise around the origin to form △A′B′C′. Then △A′B′C′ is dilated using a scale factor of 3/2 with a center of dilation at vertex A′ to form △A″B″C″. What are the coordinates of △A″B″C″? Show your work.

The coordinates of △A″B″C″ are: A″(1, 2), B″(1, -1), C″(-5, 2).

The coordinates of △A″B″C″ are: A″(0, 0), B″(2, 4), C″(4, 0).

The coordinates of △A″B″C″ are: A″(1, 1), B″(4, 4), C″(7, 1).

The coordinates of △A″B″C″ are: A″(0, 0), B″(4, 2), C″(6, 2).
