Answer:
D. no solutions
Explanation:
Solving the first inequality, we get ...
5x -4 ≥ 12
5x ≥ 16 . . . . . add 4
x ≥ 16/5 . . . . divide by 5
__
Solving the second inequality, we get ...
12x +5 ≤ -4
12x ≤ -9 . . . . . subtract 5
x ≤ -9/12 = -3/4
We simultaneously require that x is greater than some positive number while it is also less than some negative number. There are no values of x that can satisfy these inequalities. (Choice D)
