Answer:Esta es sin duda una de las comparaciones que muchos esperábamos. Gracias IGN podemos ver enfrentadas a la nueva generación de consolas Xbox One y PlayStation 4 versus su predecesoras Xbox 360 y PlayStation 3, pero sin dejar de lado esa plataforma alternativa que tanto nos gusta, el PC Gamer.
Step-by-step explanation:
First distribute the 3 so you'll have:
12+12x=12x+12
Next you subtract 12 from both sides and you'll get:
12x=12x
then you divide both sides by 12 and you get:
x=x

Answer:
The domain is all real numbers (see the explanation)
Step-by-step explanation:
we have

This is a vertical parabola open upward (the leading coefficient is positive)
The vertex represent a minimum
The vertex is the point (-5,-5)
we know that
The domain of a function is the set of all possible values of x
The range of a function is the complete set of all possible resulting values of y, after we have substituted the domain.
In this problem
The domain is the interval (-∞,∞)
The domain is all real numbers
The range is the interval [-5,∞)
All real numbers greater than or equal to -5
