Triangle def has vertices d(−4, 1), e(2, 3), and f(2, 1) and is dilated by a factor of 3 using the point (1, 1) as the point of dilation. the dilated triangle is named δd'e'f'. what are the coordinates of the vertices of the resulting triangle?

begging someone for : (

Step-by-step explanation:

Since the center of dilation is not at the origin, we can use the following formula in order to find the coordinates of the vertices of the triangle D'E'F':

Where "O" is the center of dilation at (a,b) and "k" is the scale factor.

In this case you can identify that:

Therefore, susbtituting values into the formula shown above, you get that the coordinates ot the resulting triangle D'E'F, are the following:

Vertex D' →

Vertex E' →

Vertex F' →
