QR and QS are perpendicular bisectors of the isosceles triangle XYX
so QR= QS
1/2 x + 2 = x - 10
1/2 x - x = - 10 - 2
-1/2x = - 12
x = (-12) * (-2/1)
x = 24

QS = 24 - 10
QS = 14

Answer
C . 14

Since the triangle above is isosceles, its legs are congruent. If RS was drawn, we can see visually how QR and QS are congruent also. QR and QS have the same slope, so they would travel the same distance before intersecting. Therefore, we can set up an equation where the value of QR equals the value of QS.

QR = QS
1/2x + 2 = x - 10
multiply both sides to eliminate the denominator
x + 4 = 2x - 20
24 = x
subtract x from both sides to get all "x" terms on one side
add 20 to both sides to get all non-variable terms on one side.
QS = 24 - 10
Substitute the value of x back into the value of QS
QS = 14
Combine all like terms.

!!!!! PLEASE HELP ME !!!!!

Answer:

The correct option is C : x² + (y +3)² = 9 .

Step-by-step explanation:

We know that the general equation for a circle is ( x - h )² + ( y -k )²= r², Where,

r is the radius.
(h , k) is the center.

Let the point be ( 0 , -y) , since it is on negative y axis . And the circle passes through the origin that is (0,0) . Hence the center will be 3 units down the y - axis that is ( 0 , -3) .Hence h will be 0 and y = (-3) .

Now its given that the radius of the circle is 3. So on substituting r = 3 , in standard form we have ,

⇒ ( x -h )² + ( y - k )²= r²

⇒ ( x - 0)² + { y - (-3) }² = 3²

⇒ x² + ( y + 3) ² = 3²

⇒ x² + ( y + 3)² = 9

<h3>Hence the correct option is C [ x² + ( y+3)² = 9 ] .</h3>

Note that I have attached the graph of the same .
