Responder:
El ancho del modelo de área de Averi será x² + 5x-4
Explicación paso a paso:
Deje que el área del modelo de Averi sea igual a la ecuación dada
4x² + 20x-16
Si el mayor factor común del modelo es 4, esto significa que 4 se puede factorizar fácilmente de la ecuación como se muestra;
4 * (x² + 5x-4) ... (1)
Si la fórmula para el modelo de área = Largo * Ancho
Al comparar la fórmula para encontrar el área del modelo con la ecuación 1, el ancho del modelo de área será la función entre paréntesis, es decir,
x² + 5x-4
El ancho del modelo de área de Averi será x² + 5x-4
The general vertex form is this:
v(x) = a (x-h)2 + k
where (h,k) is the coordinates of the of vertex.
and a indicates the widening or shrinking of the function compared to another parabolic function. If a become bigger, the graph becomes narrower. If a becomes negative, the graph is reflected over the x-axis.
Comparing f(x) = x2 with g(x) = -3(x+6)2 + 48, we have the following transformations:
The graph is reflected over the x-axis
The graph is made narrower.
The graph is shifted 6 units to the left.
The graph is shifted 48 units up.
From the choices we only have:
<span>The graph of f(x) = x2 is made narrower</span>
Answer:
Inverse variation
Constant = -18
Step-by-step explanation:
- Inverse or Indirect Variation where when one of the variables increases, the other one decreases (their product is constant).
- For example, y=k/x or xy =k ; the value of y varies inversely with x, y is inversely proportional to x, y is indirectly proportional to x
