0,7 1,8 5,1 6,7 .... this is a function as well!!
Six mystery books, five science books, four history books, and three adventure books add up to 18 books on the shelf.
18 divided by 9 = 2 books >> which equals 1/9 of the shelf
2/9 equals 4 books ...etc
The four history books would equal 2/9 and would be your answer!
(3j, 3k) and (3/j, 3k)
So if their x values have the same signs and their y values have the same signs, they are in the same quadrant.
If j is negative, both 3j and 3/j would be negative. If j is positive then both 3j and 3/j are positive.
And 3k is the same as 3k.
If you look on jiskha you will find the answer you will be looking for just type it in B
