Answer:
D: x < 20
Step-by-step explanation:
-4x + 16 > -64
subtract 16 from both sides because you must isolate x.
-4x + 16 - 16 > -64 - 16
-4x > -80
Then divide -4 on both sides... I believe that when you divide a number by a negative number you must flip the sign...
-4x/ -4 < -80/ -4
x < 20
(negative divided by a negative will result in a POSITIVE.)
Hope this helped... I truly apologize if this is wrong..
