These two triangles are similar and the conversion factor is 2/3. This can be found by dividing one side length corresponding to the other on the other triangle.
In this case, DF ~ AC
DF = 12
AC = 18
12/18 = 2/3
Knowing this, we can multiply 15 by 2/3 to find the length of DE because side lengths AB and DE are similar.
15 • 2/3 = 10
DE = 10
it would be 13

Answer:
Step-by-step explanation:
Let y=12x-7
Interchanging the role of x and y;
x=12y-7
x+7=12y
x+7/12=y
Therefore,f'(x)=x+7/12
