Answer:
r = 2.4
Step-by-step explanation:
First of all, note that point S(-1,6) corresponds to S(x,y), therefore:
x = -1
y = 6
Now putting the value of x and y into the equation: (x − 5)2 + (y + 3)2 = r²
(x − 5)2 + (y + 3)2 = r²
(-1 − 5)2 + (6 + 3)2 = r²
(-6)2 + (9)2 = r²
-12 + 18 = r²
6 = r²
r = √6 = 2.4
∴ r = 2.4
9x - 8y = -11
-9x + 3y = 21
Add the second equation
9x - 8y = -11
+ (-9x) + 3y = 21
-5y = 10
divide both sides by -5
y = -2
substitute y into one of the two equations in the beginning
9x - 8(-2) = -11
9x + 16 = -11
subtract 16 on both sides
9x = -27
divide both sides by 9
x = -3
The answer is (-3, -2)
x = -3
y = -2
