Answer:
i can;t copy or paste either bro
Step-by-step explanation:
Answer:
(x - 10)² + (y + 9)² = 20
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
The radius is the distance from the centre to a point on the circle
To calculate r use the distance formula
r = √(x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (10, - 9) and (x₂, y₂ ) = (12, - 13)
r = 
=
=
, hence
(x - 10)² + (y - (- 9))² = (
)², that is
(x - 10)² + (y + 9)² = 20
Answer:
14.86854, or 15
Step-by-step explanation:
y=-3x+4
this is a line with slope -3 and y intercept of 4
the line is all the points that are the solutions to the equation
D.a line that shows the set of all solutions to the equation
Number one: A B D E
number two:C
if any of these are wrong let me know ;) thank you
