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

Beyonce and Guns N Roses had the two top-grossing North American concert tours for 2016, together generating $300 million in tic

ipn [44]

Answer:

Step-by-step explanation:

B + G = 300 (million)

G = B - 38 (million)

B + B - 38 = 300

2B - 38 = 300

2B = 300 + 38

2B = 338

B = 338/2

B = 169 million <=== Beyonce

G = B - 38

G = 169 - 38

G = 131 million <==== Guns N Roses
