A) The max number of friends that can have an equal amount of beads is the max of 6 friends!
B)
The GCF of 72 and 42 is 6
Red Beads - 42 / 6 = 7
Blue Beads - 72 / 6 = 12
Each friend will have 12 blue beads and 7 red beads.
Hello,
q(x)=6x^3+19x²-15x-28
28/6=14/3
Potentiel roots are +/-1/3, +/- 2/3,+/-7/3, +/- 14/3
2x - y = 1
y = 2x -1
slope = 2
perpendicular slope = -1/2
y = mx + c
y = -1/2 + c
at point (3,2)
2 = -1/2 (3) + c
c = 2 + 3/2
c = 7/2
y = -1/2 x + 7/2
y + 1/2x = 7/2
2x - y = 1 ------------------- (1)
y + 1/2x = 7/2 -------------(2)
(1) + (2):
2x + 1/2x = 1 + 7/2
5/2 x = 9/2
5x = 9
x = 9/5 ---- sub into (1)
2x - y = 1
2(9/5) - y = 1
18/5 - y = 1
y = 18/5 - 1
y = 13/5
Ans: x = 9/5, y = 13/5
