Answer: False. here is standard form; 5x − 4y = 7
Step-by-step explanation:
The first one is 1,3,31,62 and the second answer is 1,5,8
the best would be 1.75
Step-by-step explanation:
3/4 turned into a decimal is .75 then you would add the 1 making it 1.75.
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
