Answer:
15 wins and 6 draws
Step-by-step explanation:
Here I will use indifferently the words tie and draw.
If the team played 30 and lost 9 it must have won or tied 21 games. Lets call w a win and t a tie we have that:
w + t = 21 [equation 1]
The 47 points it gained are due to either victories, that give 3 p, or ties, that give 1 p. So, the total 47 points can be expressed as:
3w + t = 47 [equation 2]
Take now equation 1 and get the value of w in function of t (or t in function of w):
w = 21 - t
Now replace it in equation t:
3(21-t) + t = 47
63 - 3t + t = 47
63 -2t = 47
subtract 63 in both sides:
-2t = -16
t = -16/-2
t = 8
So, the team draws 8 games. Lets replace it in equation 1 to get w:
w + 6 = 21
Subtract 6 in both sides:
w = 15
And the team won 15 games.
Solutions: 15 wins and 6 draws
6(x²-4x+4-4)+1=0, 6(x-2)²-24+1=0, 6(x-2)²=23, x-2=±√(23/6), x=2±√(23/6)=2±1.95789, so x=3.95789 or 0.04211 approx. These are the zeroes.
Answer:
Equation of line: y =
Step-by-step explanation:
So we have to calculate the slope. The formula is
Slope = = = =
We then need to calculate the Y-intercept.
The formula is
y - 200 = (x - 500)
y - 200 = x - 200
Add 200 to both sides
y =
There y-intercept is 0 which is the origin (0,0)
