We can say that:
8x = -2ax
8 = -2a
a = -4
22y = - 2by
22 = -2b
b = -11
37 = a² + b² - r²
37 = (-4)² + (-11)² - r²
r² = 16 + 121 - 37
r² = 100
r = 10
With all this information, we can say that:
The center of the circle is: (-4 ; -11)
and the radius of the circle is r = 10
P.S:
(a - x)² + (b-y)² = r²
a² - 2ax + x² + b² -2by + y² - r² = 0
x² + y² -2ax - 2by + a² + b² - r² = 0
Answer:
it would be a zero

Step-by-step explanation:
The second 8 in 8.8 is greater than the 0 in 8.01.
Answer:-24
Step-by-step explanation:
You multiply your numbers without the - or the +
You check ehich number is bigger and you use it symbol for the answer
Example: 3x8= 24
-8 is bigger than 3 so you use it symbol
= -24
