This circle is centered at the origin, and the length of its radius iS 6. What is

VikaD [51]

$\sf{\qquad\qquad\huge\underline{{\sf Answer}}}$

The equation of circle in standard form can be represented as :

$\qquad \sf \dashrightarrow \:(x - h) {}^{2} + (y - k) {}^{2} = r {}^{2}$

where,

h = x - coordinate of centre = 0

k = y - coordinate of centre = 0

r = radius of circle = 6 units

now, let's plug in the values :

$\qquad \sf \dashrightarrow \:(x - 0) {}^{2} + (y - 0) {}^{2} = 6 {}^{2}$

$\qquad \sf \dashrightarrow \: {x}^{2} + {y}^{2} = 36$

That's the required equation of circle.

X2 + y2 + 6x – 2y+3 = 0?<br> What is the radius of a circle with the equation

ExtremeBDS [4]

Answer:

Step-by-step explanation:

hello : write this expression

X² + y² + 6x – 2y+3 = 0 in the standard form

(x²+6x) +(y²-2y) +3 = 0

(x²+6x+9 -9) +(y²-2y+1 - 1) +3 = 0

(x²+6x+9) -9 +(y²-2y+1) - 1 +3 = 0

(x+3)²+(y-1)² = 7(the standard form)

but : 7 = (√7)²

<h2>the radius is : √7</h2>

X+y=0.5<br> x-y=1<br> elimination meathod

user100 [1]

Answer:

$x=0.75, y=-0.25$

Step-by-step explanation:

We can add the two equations to eliminate $y$ and solve for $x$ .

$x+y+x-y=0.5+1$

$2x=1.5$

$x=0.75$

Now, we can find for $y$ by using substitution:

$x+y=0.5$ (given)

$0.75+y=0.5$

$y=-0.25$

Hope this helps :)
