Coordinates of the center: ( 4, 4 )
The radius: r = 7 - 4 = 3
The equation of a circle:
( x - 4 )² + ( y - 4 )² = 3²
x² - 8 x + 16 + y² - 8 y + 16 = 9
x² + y² - 8 x - 8 y + 32 - 9 = 0
Answer:
A ) x² + y² - 8 x - 8 y + 23 = 0
Answer:
6.5 = x
Step-by-step explanation:
(x - 4)2 = 5
2*x + 2*-4 = 5
2x - 8 = 5
2x = 13
x = 6.5
X is also the height of △XYZ
Answer:
The graph in the attached figure
The point (-1,4) represent a solution
Step-by-step explanation:
we have
----> inequality A
----> inequality B
using a graphing tool
The solution is the shaded area
see the attached figure
Remember that
If a ordered pair is a solution of the system of inequalities, then the ordered pair must lie on the shaded area of the solution of the system of inequalities
The point (-1,4) represent a solution
Area of polygon = (number of sides × length of one side × apothem)/2
