You didn't supply a list. The so-called rigid transformations of translation, rotation and reflection create congruent triangles.
Generally it's dilation by a factor about a point is preserves similarity but not congruency. Any transformation which includes such scalings but is otherwise rigid also preserves similarity but not congruency.

Both of the functions are linear.
is constant.
However we are required to determine the range of 

So the only possible solution that such notation gives is -2374 so therefore the answer in terms of range is 
Hope this helps.

Let the number be n.
Then 2(7-n) = 4n, or 14 - 2n = 4n, or 14 = 6n. Then n = 7/3 (answer)
Answer:I think it would be 23. Since there is a difference of 7 between y=12 and x=5
