Answer:

Step-by-step explanation:
The equation of a circle in standard form is

You are given

In order to put the equation in standard from, we need to complete the square. Since there is no y term, the y part is simply y^2, and there is no need to complete the square for y. For x, we do have an x term, so we must complete the square in x.
Start by grouping the x terms and subtracting 45 from both sides.

Now we need to complete the square for x.

The number that completes the square will go in the blank above, and it will also be added to the right side of the equation.
To find the number you need to add to complete the square, take the coefficient of the x term. It is -18. Divide it by 2. You get -9. Now square -9 to get 81. The number that completes the square in x is 81. Now you add it to both sides of the equation.

Answer:
3
Step-by-step explanation:
Dilated has the meaning of getting larger. So in this case, if it has any meaning at all and the answer is "no answer given" then all you have to do is look at the y intercept.
The shorter line has a y intercept of 1
The longer line has a y intercept of 3
Therefore the dilation factor is 3
However if your teacher is a stickler for a better proof, then you could compare lengths.
Shorter line
Two end points
(-6,-3) (6,5)
Distance = sqrt( (-6-6)^2 + (-3-5)^2 )
distance = sqrt (144 + 64)
distance = sqrt(208)
distance = 14.42
Longer line
(-12,-5) (24,19)
distance = sqrt(24 - - 12)^2 + (19 - -5)^2 )
distance = sqrt( 36^2 + 24^2)
distance = sqrt (1296 + 576)
distance = sqrt(1872)
distance = 43.27
The best answer is =3
