Answer:
X²+y²+2x-10y+18=0 is the equation of circle
Step-by-step explanation:
Eqn of circle is: (x-h) ²+(y-k)²=r²
At (h, k) =(-1,5) and r=8 where h, k are center and r is radius.
Eqn is :(x+1)²+(y-5)²=8²
Or, x²+2x+1+y²-10y+25=8
Or, x²+y²+2x-10y+18=0 is the equation of circle
Answer: Here I simplified it and I think its right.

Hello!
You can write down what the possible numbers their are
The numbers greater than 2 are 3, 4, 5, and 6
The numbers that are odd are 1, 3, and 5
List all the numbers out in a row
3, 4, 5, 6, 1, 3, 5,
Eliminate one of the numbers that repeat
3, 4, 5, 6, 1
You put the amount of answers of the total amount of outcomes
The answer is 5/6
Hope this helps!
Answer:
C. AB/XY = AC/XZ
Step-by-step explanation:
Dilation:
A dilation is a transformation that produces an image that is the same shape as the original, but is a different size. The original figure either stretches or shrinks by a certain factor.
In the problem, the dilation is by a factor of 5 and we can see that ABC shrinks to form XYZ.
So, ABC and XYZ are similar triangles which means that the ratio of their corresponding sides will be equal:
AB/XY = AC/XZ = BC/YZ = 5
-2.31-(-5.9)= -2.31+5.9= 3.59
