for this one i got  (+5 , - 6)          3/4        are these the correct?

2.

Why is circle 1 similar to circle 2?

Circle 1: center  (2, 3) and radius 4

Circle 2: center  (2, 3) and radius 12

A. Circle 2 is a dilation of circle 1 with a scale factor of 3.

B. Circle 1 and circle 2 are reflections of each other.

C. Circle 2 is a dilation of circle 1 with a scale factor of 8.

D. Circle 1 and circle 2 have the same center.

This is the answer i got is it right? A. circle 2 is a dilation of circle 1 with a scale factor of 3

3.

I think its 1.Circle Q is a translation of circle P, 6 units up.

2.Circle Q is a dilation of circle P with a scale factor of 7

is it correct

4.

According to these three facts, which statements are true?

• Circle W has center  (−3, 0) and radius 8.
• Circle V is a translation of circle W, 2 units down.
• Circle V is a dilation of circle W with a scale factor of 2.

The radius of circle V is 16.

The center of circle V is (−5, 0).

Circle V and circle W have the same center.

Circle V and circle W are similar.

i got option 1 the radius of circle v is 16

5.

Suppose x is any positive number.

Circle 1: center (−7, 4) and radius 8x

Circle 2: center (−7, 4) and radius 2x

Why is circle 1 similar to circle 2?

A. Circle 1 is a dilation of circle 2 with a scale factor of 0.25.

B. Circle 1 is congruent to circle 2.

C. Circle 1 is a dilation of circle 2 with a scale factor of 4.

D. Circle 1 and circle 2 have the same diameter.

Is this the answer? Circle 1 is a dilation of circle 2 with a scale factor of 4.

1.    Correct   !!!!

3.   Correct !!

4. The radius of circle V is 16.  Correct!!

Also...Circles V  and W  are similar because all circles are similar...

5. Correct  !!!
