We have the following equation:
x2 + y2 + 6y - 72 = 0
Rewriting we have:
x2 + y2 + 6y = 72
Complete squares we have:
x2 + y2 + 6y + (6/2) ^ 2 = 72 + (6/2) ^ 2
x2 + y2 + 6y + (3) ^ 2 = 72 + (3) ^ 2
x2 + y2 + 6y + 9 = 72 + 9
x2 + (y + 3) 2 = 81
So, the center is:
(0, -3)
The radio is:
r = 9
Answer:
(0, -3)
r = 9
Step-by-step explanation:
[1/2]^-2= 4
[1/3]^-2=9
[1/4]^-2=16
So sum is 4+9+16=29
Hope this helps you.
Answer:
x= 0
Step-by-step explanation:
Let's first simplify the equation to make the PEMDAS process easier.
8x-10=3x-10+7x
8x-10=10x-10
Now lets start the subtracting and dividing process.
8x=10x
0=2x
0=x
It's linear and equation of the function is :
f ( x ) = 2x - 1
For the answer to the question above, <span>what is the combined length of
the original line segment and its dilated image?
</span>RS = 10
image R'S' = 20
---> 10+20=30
I hope my answer helped you. Feel free to ask more questions. have a nice day!
