<u>Equation of the Circle</u>
A circle can be completely defined knowing its center and radius. The radius is the distance from the center to any point in its edge. Since we know the center of the circle is (-10,-7) and one point in its edge is (4,4), we calculate the distance between those points:




 
        
             
        
        
        
Since you have an equation equal to both x and y, you can either substitute the equation equal to x for x or the equation equal to y for y.
x=y-1
y=4-2x
I would substitute the y in using 4-2x
x=(4-2x)-1
x=3-2x
3x=3
x=1
Then plug in x and solve for y
1=y-1
2=y

Answer:
24.44 percent
Step-by-step explanation:
F=Friday
S=Saturday
P(F or S)= 20/90+22/90-20/90=22/90
22/90 as percentage is 24.44 percent
