Length of the diameter =   sqrt ( (-12- (-8)^2) +(2-0)^2) )
  = sqrt  (16 + 4) = sqrt20 
so radius = sqrt 20 / 2 = sqrt5
so r^2 = 5


Center of the circle = coordinates of the midpoint of the diameter =

-8-12/2 , 2-0 / 2  =    (-10, 1)

(x - a)^2 + (y - b)^2 = r^2  is general form of a circle so here the circle is:_

(x + 10)^2 + (y - 1)^2 = 5  Answer

Its B

Determine translation
Mandarinka [93]
The translation moved point B(-5, -2) to B'(6, -5). Although a graph isn't necessary, it helps visualize what happened.

What happened to the x-coordinate of B?  It changed from -5 to 6, an INCREASE of 11.  So point B moved 11 units to the RIGHT.

What happened to the y-coordinate of B?  It changed from -2 to -5, a DECREASE of 3.  So point B moved 3 units DOWN.

The ages of three friends are consecutive integers. The sum of their ages is 45
Alborosie

45 = (x) + (x + 1) + (x + 2)

45 = 3x + 3

- 3

42 = 3x

/3

14 = x

45 = 14 + (14 + 1) + (14 + 2)

45 = 14 + 15 + 16

The ages of the 3 friends are 14, 15, and 16.

Compare the two ratios by entering &gt;, &lt; , or = in the box.<br> ​ 1/8 ​ 3/20 ​
Elanso [62]
In order to compare the fractions, we need to convert them into decimal form, 
1/8 = 0.125
3/20 = 0.15
As 0.15 > 0.125

In short, Your Answer would be 3/20 > 1/8

Hope this helps!

I need help ASAP help me answer questions and then I put a picture up
olya-2409 [2.1K]

Answer:

(-4,9)

Step-by-step explanation:

To solve the system of equations, you want to be able to cancel out one of the variables. In this case, it'd be easiest to cancel out the x variables. To do this, you'll want to multiply everything in the first equation by 2 (2(x-5y=-49)=2x-10y=-98). Then, you can add the two equations together. 2x and -2x will cancel out, so you'll be left with -11y=-99. Next, solve for x by dividing both sides of the equation by -11, which will give you y=9. This is your y-coordinate! At this point, you're halfway to the answer as you just need your x-coordinate. It's not too difficult to find the x-coordinate, since you just substitute 9 into one of the equations. It doesn't matter which one you choose as you should get the same answer with both. I usually substitute the y-value into both equations, though, just to make sure I'm correct. Once you put the y-value into the equations, you should get x=-4 after solving it. :)
