Answer:
No solution.
Hope this helps! Have a good day :)
we know that
1) scale factor is equal to 
2) The ratio of the perimeters of the triangles is equal to the ratio of the measures of the sides
3) the longest side of ∆ABC=[scale factor]*the longest side of ∆DEF
the longest side of ∆ABC=
the longest side of ∆ABC=
units
the answer part a) is
the longest side of ∆ABC is
units
Part b)
The ratio of the area of ∆ABC to the area of ∆DEF is equal to the scale factor squared
so
![[scale factor]^{2} =(\frac{1}{10})^{2} \\ \\ =\frac{1}{100} \\ \\ =0.01](https://tex.z-dn.net/?f=%20%5Bscale%20factor%5D%5E%7B2%7D%20%3D%28%5Cfrac%7B1%7D%7B10%7D%29%5E%7B2%7D%20%5C%5C%20%5C%5C%20%3D%5Cfrac%7B1%7D%7B100%7D%20%5C%5C%20%5C%5C%20%3D0.01%20)
therefore
the answer part b) is
The ratio of the area of ∆ABC to the area of ∆DEF is 
Basically you just have to do 100*3=300 (* multiply)
Answer:
Option A.
Step-by-step explanation:
Graph of function has been given in the figure.
Coordinates of the points lying on this graph will be
x -2 -1 0 1 2
y -10 -3 -2 -1 6
Therefore, coordinates of the points which will lie on the inverse of this function will be
x -10 -3 -2 -1 6
y -2 -1 0 1 2
Therefore, Option A. will be the answer.
