andrezito [222]

Answer:

The answer to your question is          (x + 3)² + (y + 6)² = 2

Step-by-step explanation:

Endpoints (-4, -7) and (-2, -5)

Process

1.- Find the length of the radius

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

   d = \sqrt{(-2 + 4)^{2}+ (-5 + 7)^{2}  }

   d = \sqrt{2^{2} + 2^{2} }

   d = \sqrt{4 + 4}

   d = \sqrt{8}

   Radius = \frac{\sqrt{8} }{2} = \sqrt{2}

2.- Find the center

Xm = \frac{-4 - 2}{2} = \frac{-6}{2} = -3

Ym = \frac{-7 - 5}{2} = \frac{-12}{2} = -6

Center = (-3, -6)

3.- Write the equation

                                   (x - h)² + (y - k)² = r²

                                   (x + 3)² + (y + 6)² = (\sqrt{2})²

                                   (x + 3)² + (y + 6)² = 2

Georgia [21]
3x-4y=10

or,4y=3x-10
or,y=(3x-10)/4

so,y=3/4 x-5/2

The system of equations
cupoosta [38]

Answer:

z = -12

Step-by-step explanation:

The given system of equations is:

xy/(x + y) = 1 ...........................(1)

xz/(x + z) = 2...........................(2)

yz/(y + z) = 3...........................(3)

From (1): x + y = xy

=> y = xy - x

y = x(y - 1)

x = y/(y - 1).......................................(4)

From (2): 2(x + z) = xz

=> 2x + 2z = xz

2x = xz - 2z

2x = z(x - 2)

z = 2x/(x - 2) ....................................(5)

From (3): 3(y + z) = yz

=> 3y + 3z = yz

3y = yz - 3z

3y = z(y - 3)

z = 3y/(y - 3)....................................(6)

Comparing (5) and (6)

2x/(x - 2) = 3y/(y - 3)

2x(y - 3) = 3y(x - 2)

2xy - 6x = 3xy - 6y

6(y - x) = xy .................................(7)

But from (1): xy = x + y

Using this in (7), we have

6(y - x) = x + y

6y - y - 6x - x = 0

5y - 7x = 0

5y = 7x

x = 5y/7................................................(8)

Using this in (4)

5y/7 = y/(y - 1)

1/(y - 1) = 5/7

(y - 1) = 7/5

y = 1 + 7/5

y = 12/5..........................................(9)

Using this in (8)

x = 5(12/5)/7 = 12/7 .......................(10)

Using (10) in (5)

z = 2x/(x - 2)

z = 2(12/7) ÷ (12/7 - 2)

= 24/7 ÷ -2/7

= 24/7 × (-7/2)

= -24/2 = -12

z = -12.
