Answer:
D) 
Step-by-step explanation:
If two functions 
and 
are inverse of each other, then the following conditions must be true:
i. 
ii.
Therefore, out of the four choices available, only option D matches the condition for inverse function to exist.
Therefore,
Y= mx+b
7= 2(5)+b
7= 10+b
-3= b
The answer is:
y= 2x-3
CF = FG = GC because it is equilateral triangle
So
3x + 0.8 = 2x + 3
3x–2x = 3 – 0.8
X = 2.2
Putting this value to DE
IT IS ALSO A EQUILATERAL TRIANGLE
SO
5x + 4 = 5× 2.2 +4 =
11+4 = 15
All side will be 15 of triangle CD = DC = CE = 15

1 pound is about 0.70
5 pound is 3.50
15 pound equals 11.50
9.45 pounds equals 7
14x + 70 + 20x + 8 = 180
34x + 78 = 180
34x = 102
x = 3
ABX = 14(3) + 70 = 112
CBX = 180 - 112 = 68
