Answer:
1/2 one half
Step-by-step explanation:
Answer:
The discriminant is greater than 0, so there are two real roots.
Step-by-step explanation:
Had the same Q.
Answer:
y= -1/4x+2
Step-by-step explanation:
use the slope formula to get the slope: y2-y1/x2-x1 or 1-2/4-0 subtract to get -1/4 that is the m(slope)*x in y=mx+b now for b it is the point in which x=0 so the first point has x=0 and it's y is 2 so b is 2. put it together to get y=-1/4x+2

Answer:
the diagonals bisect each other
Step-by-step explanation:
The midpoint formula tells you the midpoint M of segment XY is ...
M = (X + Y)/2
In your problem, the diagonals will bisect each other if they have the same midpoint. That is, we want to see if ...
(A +C)/2 = (B +D)/2
Multiplying by 2 can simplify our work a bit. In short, we want to test ...
A +C = B +D
(1, 4) +(-1, -4) = (4, -1) +(-4, 1) . . . . fill in the point coordinates
(1-1, 4-4) = (4-4, -1+1) . . . . . . . . . . simplify a bit
(0, 0) = (0, 0) . . . . . . . true, the midpoints are the same
The diagonals are mutual bisectors.
Answer:
90
Step-by-step explanation:
an obtuse angle is an angle from 90 - 180 degrees, so it would greater than 90 degrees
