    Answer:

    The circles are similar because the transformation rule (+ 5 , – 6) can be applied to Circle 1 and then dilate it using a scale factor of ​3/4.

    Step-by-step explanation:

    All the circles are similar.

    That is because you can transform one circle onto another by two similarity operations: translation and dilation (scale factor).

    For these two circles you have to translate the center of circle 1 to the center of circle 2, which will make that the two circles are concentric (have the same center).

    The two centers are (-6,2) and (-1,- 4). To move the center (-6, 2) to (-1,4) you have to shift it 5 units to the right and 6 units down:

    – 6 + 5  = – 1

    2 – 6 = – 4.

    After this translation, you dilate the circle with smaller radius using a scale factor equal to the ratio of the bigger radius to the smaller radius: 8/6 = 4/3.

    Enter the scale factor as a fraction in simplest form. 3/4

    The circles are similar because the transformation rule (+5 , – 6) can be applied to Circle 1 and then dilate it using a scale factor of ​3/4.
