Usando un sistema de ecuaciones, se encuentra que ese número es n = -3 o n = 3.

<h3>¿Qué es un sistema de ecuaciones?</h3>

Un sistema de ecuaciones es cuando dos o más variables están relacionadas y las ecuaciones se construyen para encontrar los valores de cada variable.

En este problema, la variable es el número n.

El quintuple de un número cuadrado disminuido en 9 da como resultado 36, o sea, la ecuación es:

5n² - 9 = 36

5n² = 45

n² = 9

n = -3 o n = 3.

When is it most handy to use a table to display information? When might you use a graph instead?
Sunny_sXe [5.5K]

Answer:

<u>Use a </u><u>table</u>

  • The display will be used to look up individual values.
  • It will be used to compare individual values but not entire series of values to one another.
  • Precise values are required.
  • The quantitative information to be communicated involves more than one unit of measure.
  • Both summary and detail values are included.

<u>Use a graph</u>

  • The message is contained in the shape of the values (e.g. patterns, trends, exceptions).
  • The display will be used to reveal relationships among whole sets of values.
