Answer:
x=1 +or- √(1)-(-8)/-2
Step-by-step explanation:
-2=-x+x^2-4
-2+4= x^2-x
2=x^2-x
x^2-x-2=0
Quadratic formula
x=-b +or -√b^2-4ac/2a
from the equation
a=1
b=-1
c=-2
Insert the variables into the quadratic formula
We have
x=-(-1) +or- √(-1)^2 - 4*(1)*(-2)/-2*(1)
x=1 +or- √(1)-(-8)/-2
=1 +or- √1+8/2
=1 +or-√9/2
=1 +or- 3/2
=1+3/2 or 1-3/2
=4/2 or -2/2
x=2 or -1
Answer:
Slope:-1/4 y-int: 3
Step-by-step explanation:
You can you the formula y1-y2/x1-x1 or you can look at it and find out if that makes sense
You would start by multiplying the radius by its self to get 9.6 * 9.6= 92.16 then you would mutiply that by pie 92.16 * 3.14 = 289.38 and you would round that to 289.4

the middle line is 12 feet and the dot is about in the middle of the line
Answer:
84*(1/4)^x
Step-by-step explanation:
84 is the constant as it is the starting amount. However each round (x because the amount of rounds is constantly changing) divides the team by 4 or multiplies by 1/4 (Reciprocal).
So, if you wanted to see if the amount of teams after three rounds you would do:
84 * 1/4 * 1/4 * 1/4. However, any number times itself is an exponent, so we would simplify to 84³. But due to the fact we do not know how many rounds we are going to calculate we change the exponent to x.
