Answer:
x^2 +y^2 -40x -24y -81 =0
Step-by-step explanation:
We can write the equation of a circle in the form
(x-h)^2 + (y-k)^2 = r^2
Where (h,k) is the center and r is the radius
Assuming that Pamela's cabin is the center
( x-20)^2 + (y- 12)^2 = 25^2
We want to get to general form
x^2 + y^2 + Dx + Ey + F = 0,
Distributing
x^2 -40x +400 + y^2 -24y +144 = 625
x^2 +y^2 -40x -24y +544 -625 =0
x^2 +y^2 -40x -24y -81 =0
Answer:
f(6) = 24
Step-by-step explanation:
f(x) = x^2 - 2x
Let x = 6
f(6) = 6^2 - 2(6)
= 36 - 12
= 24

Answer:
Step-by-step explanation:
x = 10+2y
Answer:
Step-by-step explanation:
1. Draw a line down the middle of the equal sign .
2.Divide 4x/4. Which equals x.
3. Divide 6/4. Which equals 1 and 2/4 or 1 and 1/2.
4. X=1 2/4
5. Check=
Y=4x+6
Plug 4 with 1 2/4. Which equals 6.
6+6=12
X=1 2/4 Y=12
