Dilate triangle abc by a factor of 2 around point a. what are the coordinates of b q1 (1,0) q2 (1,-1) q3 (1,-2) q4 (2,-4)

Option 3: (1,-2)

Step-by-step explanation:

From the given figure it is clear that the vertices of triangle ABC are A(1,4), B(1,1), C(4,1).

If a figure dilated by the factor k and the center of dilation is point (a,b), then the rule of dilation is

The figure ABC dilated by the factor 2 and the center of dilation is point A(1,4).

The coordinates of B after dilation are

The coordinates of B after dilation are (1,-2).

Therefore, the correct option is 3.

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.
