Yes it does match D) but the word between them is OR, not AND

 6 > -4x+5 OR 12 ≤ -3x+5

4x > -1   OR  3x ≤ -7

 x >    OR x ≤ 

That's the same as 

 x ≤  OR  x >    

 x ≤  OR  x > 

The graph of that is

<====================⚫------------------⚪================================> 
-4          -3          -2          -1           0           1           2  

The circle on the left is closed because the inequality is ≤ and the one on 
the right is open because it's >.

and the interval notation for that is

  (-∞,-7/3] ∪ (-1/4, ∞)

The interval notation is just an abbreviation for the graph on the 
number line above:

The ] indicates that  IS included in the solution set,
The ( indicates that  is NOT included in the solution set,
the ∪ indicates "OR", indicating a "jump" in the shading.
