Answer:

\Huge \boxed{2x-3=-21}

Step-by-step explanation:

Let the number be x.

The difference of two values is the result from subtracting them.

2x-3=-21

Add 3 to both sides.

2x=-18

Divide both sides by 2.

x=-9

The number is -9.

Find the factored form of<br> 11m + m2 = 0
Vlada [557]

Answer:

Step-by-step explanation:

If you want to factor

m^2+11m=0,  you could throw that into the quadratic formula with a = 1, b = 11 and c = 0, but the easier thing to do is to factor out what's common in those 2 terms.  m is common, so when we factor it out:

m(m+11)=0

That's the factored form.

By the Zero Product Property, either

m = 0 or m + 11 = 0.  

So the 2 solutions to this are

m = 0 or m = -11

Not sure how far you need to go with this.

Identity the construction that the figure represents
nordsb [41]

The construction is the construction of the Perpendicular bisector.

<h3>How to illustrate the information?</h3>

The steps for the construction of perpendicular bisectors are as follows:

Open the compass more than half of the distance between A and B, and scribe arcs of the same radius centered at A and B.

Call the two points where these two arcs meet X and Y. Draw the line between X and Y.

So, the point where this line meets the line segment; M is called the mid point and the line XY is the perpendicular bisector of the line AB.

The figure is a construction of perpendicular bisector.

Por qué crees que el valor de la media no aparece en la tabla y es un número decimal?
vovikov84 [41]

La media no aparece en la tabla ya que se requiere un calculo para encontrarla, además, es un número decimal pues corresponde a la suma de los resultados dividida en el número de días.

<h3>¿Qué es la media?</h3>

En matemáticas, la media o promedio corresponde a la suma de todos los valores dividida en el número total de valores. En este caso la media corresponde a la suma de las temperaturas dividida en el número de días.

Calcular la media:

Usando la formula anterior, calculemos la media:

  • 16 + 19 +17 + 20 + 22 + 18 +15 = 127/7 = 18.7

El valor de la media es 18.7, al respecto se puede observar que:

  • Este valor no aparee en la tabla pues no corresponde a la temperatura de ningún día sino que debe ser calculado.
  • Este valor es decimal, lo que se común al hallar la media ya que se suman todos los valores y se dividen por un número determinado.

Nota: Esta pregunta esta incompleta. Aquí esta la parte faltante:
