Answer:
Final graph is attached.
Solution is x=2, y=3
Step-by-step explanation:
As we have to solve by graphing to let's graph y=2x-1 first.
we are free to plug any number for x say x=0 and x=2
when x=0 then y=2x-1 changes to
y=2(0)-1=0-1=-1
Hence point is (0,-1)
Similarly
when x=2 then y=2x-1 changes to
y=2(2)-1=4-1=3
Hence point is (2,3).
Now we graph both points (0,-1) and (2,3) then join them by a straight line.
We repeat exactly same process for other line y=-x+5 and get points (0,5) and (2,3)
Now graph both to see the intersection point of both lines
We see that both lines intersect at point (2,3)
<u>Hence final answer is (2,3) or we can also write x=2, y=3.</u>
Answer:
Perimeter of a polygon with 31 sides = (side length) x 31 = 279 units
Area of a polygon with 31 sides = (n x Side2 x cot (Π/n))/4 = (n x 92 x cot (Π/31))/4 = 6173.16 square units
Sum of the interior angles of a polygon with 31 sides = (n-2) x 180 degrees = (31-2) x 180 degrees = 5220 degrees
Interior Angle of a polygon with 31 sides = (n-2) x 180/n degrees = (31-2) x 180/31 degrees = 168.38 degrees
Exterior angle of a polygon with 31 sides = 180 - Interior Angle = 180 - 168.38 = 11.61 degrees
Inradius = Radius of In-circle = (side length) x cot (Π/31) = 9 x cot 5 = 88.5 units
Circumradius = Radius of Circum-circle = (side length) x cosec (Π/31) = 9 x cosec 5 degrees = 88.96 units
Symmetry Group = D31 31 rotational symmetries and 31 reflection symmetries. The "D" stands for di-hedral.
