Answer: -2
Step-by-step explanation:
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
15.36 / 3 = $5.12
Divide by 3 on both sides to get the value of 2 bags on popcorn.
Answer:
Fourth answer
Step-by-step explanation:
-7-4=-3
Answer:
x=1/2, x=5
Step-by-step explanation:
2x^2-11x+5=0
Factor them
(x-0.5)(x-5)
x=0.5 or 1/2
x=5
