Given:
A figure of dilation and the center of dilation is O.
To find:
The value of y.
Solution:
The distance between center and vertex of image (d') is proportional to the distance between center and the corresponding vertex of original figure (d).
Where, k is the scale factor or constant of proportionality.
So, the scale factor for the given dilation is
We know that,
Divide both sides by 9.
Therefore, the value of y is 12.
Subtract 5 (Cameron) and 2 (Karlee) from 49.
Why: Denise's age is basically the basic number. Karlee would be 2 years older, so subtract 2 from 49. You get 47. Cameron is 5 years older than Denise, so subtract 5. You get 42 and divide that by 3 since there are 3 people.
49 - 7 = 42
42 divide by 3 = 14
Check:
14 + 5 = 19
14 + 2 = 16
14 + 0 = 14
19 + 16 + 14 = 49
19 (Cameron) - 16 (Karlee) = 3 years older
16 (Karlee) - 14 (Denise) = 2 years older
19 (Cameron) - 14 (Denise) = 5 years older
Hopes this helps!
the possibilities are probably b, using the elimination method
Answer:La media aritmética es la suma de todos los datos dividida entre el número total de datos :)
Y=24 Y-12=12 Y=12+12 Y=24
(X-12) = 12
X = 12+12
X=24
