What is the solution to this equation ?<br><br><br> x + 9 = -4
PolarNik [594]

Isolate the x. Note the equal sign. What you do to one side, you do to the other.

Subtract 9 from both sides

x + 9 (-9) = -4 (-9)

x = -4 - 9

x = -13

-13 is your solution

hope this helps

The point (5,-6) lies on a circle and the center of the circle is at the point (5,-8).
mario62 [17]

Answer:

A.  

(x - 5)^2 + (y + 8)^2 = 4

Step-by-step explanation:

The equation for a circle in center radius form is

(x-h)^2 + (y-k)^2 = r^2  where (h,k) is the center and r is the radius

We need to determine the radius, from the two points which is the distance

d = sqrt( (x2-x1)^2 + (y2-y1)^2)

  = sqrt( (5-5)^2+( -8--6)^2)

  = sqrt(0+ (-8+6)^2)

  = sqrt( 0+(-2)^2)

  = sqrt(4)

  = 2

The radius is 2 and the center is (5,-8)

(x-5)^2 + (y--8)^2 = 2^2

(x-5)^2 + (y+8)^2 = 4

Someone please answer this, ill give you brainliest and your getting 100 points.
andrew11 [14]

Answer:

Step-by-step explanation:

First sequence : 10,9.5,9,8.5,...

Let's see the difference between 2 numbers :
10 - 9.5 = 0.5
9.5 - 9 = 0.5
9 - 8.5 - 0.5

So on and so on. So, the common difference between these numbers are 0.5

Next sequence : 200,100,50,25, ...

We see, to get from one number to another, we divide it by 2 / multiply it by 1/2.

200 x 1/2 = 100
100 x 1/2 = 50
50 x 1/2 = 25

So on and so on. So, the common ratio of these numbers are 1/2.
