Okay, So We Need To First Look At This:
x/5 + 6 = 36.
So, We Need To Solve.
First, Subtract 6.
x/5 = 36 - 6
36 - 6 = 30
x/5 = 30
Now, Multiply.
x = 30 * 5
30 * 5 = 150
So:
X = 150
B. 30% is the better deal
.3x12=3.6
(:
I think the correct answer would be C. hope this helped !
If you are moving the center of circle 2 to the the center of circle 1, then the translation rule is (x,y) ---> (x+4, y+10).
Note how x = 1 turns into x = 5. So we add 4
Also, y = -2 turns into y = 8. We add 10
The scale factor to turn the radius r = 4 into r = 8 is 2. Basically we double the radius. We can divide the two radii to see 8/4 = 2
----------------------------------
Summary:
To go from circle 2 to circle 1, we apply these two transformations
translation: (x,y) ---> (x+4, y+10)
dilation: scale factor 2
note:
if you want to go backwards, go from circle 1 to circle 2, then undo the transformations above
