Question 71865
choose the inequality that is equivalent to X > -9 
Please show me how to find out what the answer is?

Solve each possible answer for "x" to see which is x>-9
 
(a) 5x>45
Divide by 5 to get x>9;  nope
------------
 (B) -5x < 45
(Remember: dividing or multiply by a negative reverses the inequality.
Divide by -5 to get x>-9; that's the correct answer
-------
(c) -5x > -45
Divide by -5 to get x<9; nope
---------
 (d) -5x < -45 
Divide by -5 to get x>9; nope
