Answer: Rotate 180 degrees around point B</h3>
Explanation:
Point A(-3,1) moves to A ' (1,1). The line through these two points is y = 1.
Point C(-3,3) moves to C ' (1, -1). The line through these two points is y = -x
These two lines intersect at point B(-1,1) which is the invariant point, aka fixed point. It is the center of rotation.
Notice how points A, B and A' are collinear (i.e. they are on the same line). The same can be said about points C, B and C'.
Because of these two sets of collinear points, it means we have a 180 degree rotation going on.

Answer:
The answer is t + 27
Step-by-step explanation:
Yes. a negative subtracting a negative equals a positive, therefore it would be 7+12 which would equal 19. your friend is correct.
Answer:
14 and 15
Step-by-step explanation:
14 and 15
14 x 14 = 196
15 x 15 = 225
(23)^8 b/c when multiply powers you add the exponent values together
