Ryne is asked to graph this system of equations: 6x - 4y = 2
-2y+ 3x = 1
How many times will the lines intersect?
A. There is no way to tell without graphing the lines first.
B. The lines will intersect infinitely many times, because they are
identical.
O
C. The lines will not intersect, because this system has no solutions.
O
D. The lines will intersect once, because this system has one
solution.

  best answer for the question.1.     divide  7/24  by  35/48  and reduce the quotient to the lowest fraction. 

An annual marathon covers a route that has a distance of approximately 26 miles. winning times for this marathon are all over 2 hours. the following data are the minutes over 2 hours for the winning male runners over two periods of 20 years each. earlier period 14 12 15 22 13 10 19 13 9 14 20 18 16 20 23 12 18 17 6 13 recent period 7 11 7 14 8 9 11 14 8 7 9 8 7 9 9 9 9 8 10 8 (a) make a stem-and-leaf display for the minutes over 2 hours of the winning times for the earlier period. use two lines per stem. (use the tens digit as the stem and the ones digit as the leaf. enter none in any unused answer blanks. for more details, view how to split a stem.) minutes beyond 2 hours earlier period 0 1 2 (b) make a stem-and-leaf display for the minutes over 2 hours of the winning times for the recent period. use two lines per stem. (use the tens digit as the stem and the ones digit as the leaf. enter none in any unused answer blanks.) minutes beyond 2 hours recent period (c) compare the two distributions. how many times under 15 minutes are in each distribution
