Answer 1

To find the coordinates of the new vertices \( A'B'C' \) after dilating the triangle with a magnitude of 3 in reference to the origin, you need to multiply the coordinates of each vertex by the dilation factor.

The original coordinates of the vertices are:

• \( A(-2, 5) \)
• \( B(0, 3) \)
• \( C(6, -3) \)

Now, we will perform the dilation:

1. Dilation of A: \[ A' = (3 \times -2, 3 \times 5) = (-6, 15) \]

2. Dilation of B: \[ B' = (3 \times 0, 3 \times 3) = (0, 9) \]

3. Dilation of C: \[ C' = (3 \times 6, 3 \times -3) = (18, -9) \]

So, the coordinates of the new vertices \( A', B', C' \) after dilation are:

• \( A'(-6, 15) \)
• \( B'(0, 9) \)
• \( C'(18, -9) \)

Therefore, the response corresponding to your problem is:

A′(−6,−15), B′(0,9), and C′(18,−9).
