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

843/24= 35.13
Answer:
D.
Step-by-step explanation:
Answer: Y = -7X-2
Step-by-step explanation:
if there are two co-ordinates (x1,y1) and (x2,y2).
If the line is passing through these co-ordinates
Then Slopw of the line = (y2-y1)/(x2-x1)
We have one co-ordinate (-1,5) let it be (X1,Y1)
Let second co-ordinate be (X,Y)
Slope = -7 = (Y-5) / (X-(-1))
-7 = (Y-5)/(X+1)
Y-5 = -7 (x+1)
Y-5 = -7x-7
ADDING 5 ON BOTH SIDES OF THE EQUATION
Y-5+5 = -7X-7+5
Y = -7x-2
Answer:
A. $3.59
Step-by-step explanation:
Okay so wrapping paper 4.99 she got three. So we would take 4.99 and subtract 80%. We would get 0.998. We multiply this by three because that's how many she got. After multiplying it's 2.994, rounded just 2.99. She payed 2.99 for wrapping paper. Now with the candy canes, we take 2.99 and subtract 80%. 0.59. Added we get 3.58, and we can go ahead and round that up to $3.59. Before tax she payed $3.59.
