Hello,
4x²-x-3=0
==>(2x)²-2*1/2*x+1/4-3-1/4=0
==>(2x-1/2)²-13/4=0
==>(4x-1)²-13=0
==>(4x-1-√13)(4x-1+√13)=0
==> x=(1+√13)/4 or x=(1-√13)/4
Answer:
Perpendicular
Step-by-step explanation:
Put all the points on a graph.
Parallel means that the lines that have the same slope and different y-intercepts. Lines that are parallel to each other will never intersect.
On the graph we made we can see that the lines will have to intersect because the points are in positions that no matter which points we chose to connect together, they would intersect with the other line.
Well 88.5 +88.5+56.2+56.2= 289.4 meters in perimeter
Answer:
(1/2, -1/2)
Step-by-step explanation:
The center of the circumcircle is the midpoint of the hypotenuse of the inscribed right triangle, so is the midpoint of UW.
(U+W)/2 = ((-3, 2) + (4, -3))/2 = (1, -1)/2 = (1/2, -1/2) . . . . center
_____
If you mean something else, we need a better description. There are an infinite number of points on the circumference of the circle, none of which is listed here.
