Answer:
Step-by-step explanation:
We have the inequality:
Solve. Divide both sides by -2. Since we are dividing by a negative, we must flip the inequality sign. Thus:
Add 5 to both sides:
Therefore, our solution is all numbers greater than 11 .
This means that if we substitute any number greater than 11 into our original inequality, the inequality will be true.
Answer:
second and last one
Step-by-step explanation:
the less a negative the closer it is to zero which means it's closer to being a positive
(x+y-3)(x+y+3) = x^2+xy+3x+xy+y^2+3y-3x-3y-9 = -9+x^2+y^2+2xy
