Here is a quick sketch of Venn diagram if there were 100 % students:
if 10 reprsents 20 % then there were 50 students in the poll
25 choose only Blue 15 only red 10 both
b/a = 1/2
c/b = 3/4 b/a * c/b = c/a = 1/2 * 3/4 = 3/8
-7(1+5m)-29<300+7m expand Left side
-7 - 35m - 29 < 300 + 7m simplify by gathering 'like' terms
-42m < 336 divide by - 42 ( this reverses the < to > )
m > 336/(-42)
m > -8
x cannot = 2 ( from the denominator)
NUMERATOR factors to x ( x+2)(x-4) the (x+2) in the numerator and denominator cancel and you are left with:
x^2 - 4x = 5
x^2 - 4x - 5 = 0
(x-5)(x+1) = 0 so x = 5 or -1 sum = 4
Here is POINT - slope form
y - -1 = -5/4 ( x - - 4) re-arrange to slope intercept form
y +1 = - 5/4x - 5
y = - 5/4 x -6
I do not know...I just uploaded this one..... Is the file on your computer? When you 'browse' for it does it show up in the list in the folder where it is stored ? .....is it in the proper format (like .jpg ) ?
p1 = p2 -3
p2
p3 = p2 -2
p4 = p2+1 summed = 20
p2 - 3 + p2 + p2-2 + p2 + 1 = 20
4 p2 -4 = 20
p2 = 6 then p4 = 7
One BIG shape 7 x 9 = 63
minus the cut out 2 x 3 = 6
63 - 6 = 57 m2
6 teams must play 5 other teams twice in each dividsion (2) = 6 x 5 x 2 x 2 =120
and 6 teams each must play other division 6 teams once = 6 x 6 x 2 = 72
this is a total of 192 games....BUT each game involves TWO teams soooo 192/2 = 96 games total
