C because the x-axis and the y-axis are switched, basically.
The answer is: " x < -3 " .

Given:
______________________
" 9(2x + 1) < 9x – 18 " ;
First , factor out a "9" in the expression on the right-hand side of the inequality:
9x – 18 = 9(x – 2) ;
and rewrite the inequality:
_____________________
9(2x + 1) < 9(x – 2) ;
Now, divide EACH SIDE of the inequality by "9" ;
[9(2x + 1)] / 9 < [9(x – 2)] / 9 ;
to get:
2x + 1 < x – 2 ;
Now, subtract "x" and add "2" to each side of the inequality:
2x + 1 – x + 2 < x – 2 – x + 2 ;
to get:
x + 3 < 0 ;
Subtract "3" from EACH SIDE ;
x + 3 – 3 < 0 – 3 ;
to get:
" x < -3 " .

Answer:
I think that the answer is 2 power n , so A is the correct choice .
7 / 12 = 0.583333333
Divide them all to see which one equals 0.583333333.
A.
8 / 13 = 0.615384615
B.
10 / 15 = 0.666666667
C.
14 / 19 = 0.736842105
D.
21 / 36 = 0.583333333
Therefore, your answer is D.
