Those are a lot of questions, try to break up your posts into smaller bits
Most of your answers are correct, I found a few that had errors.
(wish you had "numbered" your questions)
<<Q:solve using multiplication principle then graph
- 15x > - 75
A: {x | x > 5}
when graphing the circle is open on the 5 and goes to the right >>
When you multiply or divide an inequation by a negative, you have to reverse the inequality sign, so ...
- 15x > - 75
x < 5 would be your inequation, the graph would go to the left.
You made the same error in
<<Q: solve using the multiplication principle
- 6x < - 18
the solution set is {x | x ? ?}
A: {x | x < 3} >>
should be x > 3
in
<<Q: solve
y - 3 > - 13
the solution is {x | x > ?}
A: {x | x > - 10} >>
you switched from y's to x's, why?
