X² + y² = 8

ohaa [14]

Answer:

$(2,2)~ \text{and}~ (-2,-2)$

Step by step explanation:

$x^2 +y^2 =8~~~~~~...(i)\\\\x-y=0~~~~~~~~~...(ii)\\\\\text{From (ii):}\\\\x-y = 0 \implies x = y\\\\\text{Substitute x = y in eq (i):}\\\\~~~~~~y^2 +y^2 =8\\\\\implies 2y^2 = 8\\ \\\implies y^2 = \dfrac 82\\\\\implies y^2 = 4\\\\\implies y = \pm\sqrt 4\\\\\implies y = \pm 2\\\\\text{Substitute y = x in equation (i):}\\ \\~~~~~~x^2 +x^2 = 8\\ \\\implies 2x^2 = 8\\\\\implies x^2 = \dfrac 82\\\\\implies x^2 = 4\\\\\implies x = \pm\sqrt 4\\\\\implies x = \pm2\\\\$

$\text{Hence,}~ (x,y) = (\pm2, \pm 2)$

*100 points* A circle has a diameter with endpoints (-7, -1) and (-5, -9).

earnstyle [38]

Diameter

√(-7+5)²+(-1+9)²
√2²+8²
√4+64
√68
2√17

Radius

2√17/2
√17units

Now

Centre

(h,k)

(-7-5/2,-1-9/2)
(-12/2,-10/2)
(-6,-5)

Equation

(x-h)²+(y-k)²=r²
(x+6)²+(y+5)²=(√17)²
(x+6)²+(y+5)²=17

Option A
