Question Which sequence of transformations maps pre-image ABC to image A′B′C′ ? Triangle ABC was reflected over the y-axis and t
hen dilated by a scale factor of 2. Triangle A B C, was reflected over the , y, -axis and then dilated by a scale factor of 2. Triangle ABC was reflected over the y-axis and then translated 2 units up and 2 units to the right. Triangle A B C, was reflected over the , y, -axis and then translated 2 units up and 2 units to the right. Triangle ABC was rotated 90° counterclockwise and then dilated by a scale factor of 2. Triangle A B C, was rotated 90° counterclockwise and then dilated by a scale factor of 2. Triangle ABC was rotated 90° counterclockwise and then translated 2 units up and 2 units to the right. Triangle A B C, was rotated 90° counterclockwise and then translated 2 units up and 2 units to the right.

Step-by-step explanation:
Properties of a circumcenter;
1). Circumcenter of a triangle is a point which is equidistant from all vertices.
2). Point where perpendicular bisectors of the sides of a triangle meet is called circumcenter of the triangle.
From the picture attached,
9). AG = GB = GC = 21
10). BC = 2(DC)
= 2×16
= 32
11). By applying Pythagoras Theorem in ΔGFB,
GB² = GF² + FB²
(21)² = GF² + (19)²
441 = GF² + 361
GF² = 441 - 361
GF =
GF = 8.9
12). By applying Pythagoras theorem in ΔGDB,
GB² = DG² + BD²
(21)² = (DG)² + (16)² [BD = DC = 16]
DG² = 441 - 256
DG = √185
DG = 13.6
The equation of the graph is given as y = (2/5)x - 5.
You have to figure out which of the choices equals the equation given,
y = (2/5)x - 5.
You could solve each of the answer choices for y, but since each choice is in the format x - (m)y = b, you can put the given equation in that format too.
