to get there you need at least three level 8's. To get one level 8, you need at least 3 level 7's. And so on and so forth until you are at level 1. The trick though is that if I have 5 of a certain level, I can make 2 of the next. If I have 8, I can make 3. How many level 1's would i need to make a level 9, using the fewest possible level 1's?
nswers so I'm confused, the question is, "Suppose two different lines have both negative (but different) slope. Can these two lines be perpendicular? If Yes, give an example. If No, explain."
