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.
The square root of 3 would be irrational. 0 and 10 are whole numbers so we can mark them out right off the bat. When you turn 3/7 into a decimal, it terminates making it rational as well.
Answer:
a) 7/10
b) There is no improper fraction form for this
