Answer:
y = 3x -18 ( where y = balls sent back by Rudolf; x= balls given to Rudolf)
Step-by-step explanation:
x (Balls given) y( Balls sent back)
8 6 Δy/Δx = (27-6)/(15-8) = 3
15 27
25 57 Δy/Δx = (57-27)/(25-15) = 3
Observing the number sequence shows constant gradient and as such we can use equation of a straight line to relate the two variables.
Using the equation of a straight line we have:
(y-y1)/(x-x1) = (y2-y1)/(x2-x1)
y-6/x-8 = (27-6)/(15-8)
y-6/x-8 = 3
y-6 = 3(x-8)
y-6 = 3x - 24
y = 3x-18
Answer:
Step-by-step explanation:
There could be 2 3 4 6 or 12. You can use any number that divides evenly into 12. I don't think you can use 1 because the question says members. The next question is, do you include Sharon in the group (so she gives herself a share) and again I will answer yes. She has to get something out of the deal.
2: each member gets 3 red and 3 white. ( don't say 6 red and 6 white.)
3: Each member gets 4 in total 2 red and 2 white each
4: Each member gets 4 in total. This can be split 2 ways.
6: Each member gets 2 in total: 1 red and 1 white.
12: Each member gets 1. 6 get red and the others get white.
Answer:
x=-4 y=-7
Step-by-step explanation:
-4x+y=9 get y alone
add 4x both sides
y=4x+9
insert into y=2x+1
2x+1=4x+9
subtract 1 both sides
2x=4x+8
subtract 4x both sides
-2x=8
divide by -2
x=-4
y=2x+1
y=2(-4)+1
y=-8+1
y=-7
check
-4(-4)+(-7)=9
-16+(-7)=9
9=9
x=-4
y=-7
