-0.96
If you look up that exact equation on google you get -0.952380952 and you just round it to get -0.96
N^2 because 2n is the same as n+n, but n^2 is the same as the product of n and n
The quadratic formula is the result of completing the square for ax^2+bx+c=0 when a,b, and c are unknown values. This result is:
x=(-b±√(b^2-4ac))/(2a), we have x^2-x-2=0 so
x=(1±√(1+8))/2
x=(1±√9)/2
x=(1±3)/2
x=-1 and 2
Answer:
the slope of the line is 4
m = 4
y-intercept is -8
y = 4(0) - 8 = 0 - 8 = -8
I think that the answer could be D
