From -4 to 1 (range equals the y values)
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

Answer:
13 rabbits 15 turtles
Step-by-step explanation:
T + R = 28
3T +5R = 110
Multiply the first by -3 to eliminate T
-3T -3R =-84
3T + 5R = 110
AD BOTH ( T will be cancelled)
2R = 26
R = 13 (13 rabbits)
28-13= 15 (15 turtles)
13x5 = 65
15x3 = 45
13x5 =65
45+65 = $110
Answer:
3(x + 5)(x+ 5)
Step-by-step explanation:
3x² + 30x + 75
Here's one way to do it.
Step 1. Factor out the highest common factor of all three terms.
You can factor out a 3.
3(x² +10x +25) = 0
Step 2. Factor the remaining polynomial
We must find two numbers whose product is 25 and whose sum is 10.
A little trial-and-error gives us 5 and 5.
5 × 5 = 25; 5 + 5 = 10
We can factor the expression as
3(x + 5)(x + 5)
