Hey there! I'm happy to help!

If you reflect a point across the x-axis, you have (x,y)⇒(x,-y). If you reflect across the y-axis, you have (x,y)⇒(-x,y). A 180° rotation is the same thing as reflecting across both the x and y axes. This means that the rule for rotating the point with coordinates (x,y) 180° clockwise about the origin is D. (x,y)⇒      (-x,-y).

Have a wonderful day! :D

When sarah was 6 months old, she was 21 inches tall and her head had a diameter of 4.5 inches. now, at 20 year sold, she is 6 ft
pochemuha
Answer: Yes, she could be considered similar to herself at 6 months of age.

In mathematics, the concept of similarity is about proportion relationships. In this problem, we are discussing the relationships between age, height and diameter. We are not discussing the absolute value of the numbers themselves.

For example in Geometry, a very small triangle can be similar to a very large triangle if all the angles of the triangle are congruent. The size doesn't matter.
