Answer:
Step-by-step explanation:
The standard form for the equation of a circle is
From the info given, we have the center, (h, k) as (5, -3) and the x and y coordinates of (2, 5). We will use these to solve for r-squared, then plug back in what we need to write the equation.
which simplifies to
and
so
Filling in the equation:
Answer:
22,-89
Step-by-step explanation:
let the numbers be x and y .
x+y=-45
x-y=-89
add
2x=--134
x=-67
-67+y=-45
y=-45+67=22
Answer:
J (-4 , 1) -> J' (1 , 4)
K (-2 , 1) -> K' (1 , 2)
L (-2 , 5) -> L' (5 , 2)
Step-by-step explanation:
clockwise rotation 90°: (x,y) -> (y,-x)
J (-4 , 1) -> J' (1 , 4)
K (-2 , 1) -> K' (1 , 2)
L (-2 , 5) -> L' (5 , 2)
