<span>To answer the question above first we need toclarify what the inequality is actually saying:
7 - 9x - (x + 12) </= 25 (simplify)
-5 - 10x </= 25 (add 5 to both sides)
-10x </= 30 (divide by -10 to get x)
x >/= -3 (don't forget to flip the signs when you divide by a negative number)
So this says x is greater than or equal to -3, so which of these statements is not a way to represent that?
I'd say it's the second one. x is greater than not less than.</span>
Answer:
1. (-3, 4) 2. (5/2, 15/2) 3. (9/5, -36/5) 4. (-2, 1)
