circle a has center of (6,7) and a radius of 4 and circle b has a center of (2,4) and a radius of 16. what steps will show that circle a is similar to circle b

the choices are:
translate circle a using the rule (x+4,y+3).
rotate circle a 45° about the center.
dilate circle a by a scale factor of 4.
reflect circle a about the origin.

Dilate Circle A by a scale factor of 4.

Step-by-step explanation:

Figure 1 shows Circles A (red) and B (green) before any transformations.

Figure 2 shows Circle A dilated about its centre by a factor of 4.

It is now apparent that every radius in A' has a corresponding radius in B, so the circles are similar.

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
