Determina el centro,radio y gráfica de la circunferencia:(x+2)2 + (y-3)2=121
Sergeu [11.5K]

Answer:

La ecuación genérica para un círculo centrado en el punto (a, b), de radio R, es:

(x - a)^2 + (x - b)^2 = R^2

Entonces si miramos a nuestra ecuación:

(x + 2)^2 + (y - 3)^2 = 121

Tendremos el centro en:

(-2, 3)

el radio está dado por:

R^2 = 121

R = √121 = 11

La gráfica de esta circunferencia se puede ver en la imagen de abajo.

Gennadij [26K]

Answer:

x = -13/5

Step-by-step explanation:

let x be the number

8x + 6 = 3x - 7

move variables to left and numbers to right

8x - 3x = - 7 -6

5x = -13

x = -13/5

Xelga [282]

miles= 30 × hours

use this equation to fill out the graph and find out what y (miles traveled) equals.

for example, multiply 5 (the hours passed) by 30. Your answer would be 150, which is the miles the biker would travel in 5 hours.

Y varies directly as x.if y=-5 when x =15find x when y=3
Tpy6a [65]
Y=kx
-5=k(15)
-5/15=k
-1/3=k
now,
y=-1/5x
3=-1/5x
3×5=-1(x)
15=-1(x)
multiplying both sides by -1,we get
-15=x
