Este famoso dibujo se encuentra en la biblioteca real De Turín. Esta realizado en tiza roja y mide 33 cm de alto y 21,6 cm de an
cho. Si completa, el cuadro mágico con los números del 1 al 16 descubrirá el año en el cual fue realizado este dibujo ( la suma mágica de este cuadrado es 34)
1 answer:
<h2>Respuesta:</h2>
1513
<h2>Explicación paso a paso:</h2>En este problema, estamos hablando del autoretrato de Leonardo Davinci. Para la resolución de este problema, necesitamos usar el cuadrado mágico de forma tal que al colocar en cada casilla los números del 1 al 16 sin repetición, entonces los números de cada fila, columna y diagonal sumen 34. De esta manera, si se colocan los números así, el resultado obtenido es 34. En la figura de abajo se encuentra el cuadrado mágico resuelto:
Columna 1:
Columna 2:
Columna 3:
Columna 4:
Fila 1:
Fila 2:
Fila 3:
Fila 4:
Diagonal 1:
Diagonal 2:
Finalmente, esta pintura fue realizada en el año 1513, que son los números de las casillas en negro.

Answer:
Step-by-step explanation:
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
2*x-y-(4)=0
Step 1:
Equation of a Straight Line
Solve 2x-y-4 = 0
Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line 2x-y-4 = 0 and calculate its properties
Graph of a Straight Line :
( see attatchment)
Calculate the Y-Intercept :
Notice that when x = 0 the value of y is 4/-1 so this line "cuts" the y axis at y=-4.00000
y-intercept = 4/-1 = -4.00000
Calculate the X-Intercept :
When y = 0 the value of x is 2/1 Our line therefore "cuts" the x axis at x= 2.00000
x-intercept = 4/2 = 2
Calculate the Slope :
Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is -4.000 and for x=2.000, the value of y is 0.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 0.000 - (-4.000) = 4.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = 2
Geometric figure: Straight Line
1. Slope = 2
2. x-intercept = 4/2 = 2
3. y-intercept = 4/-1 = -4.00000
- clarification for graph - green means rise red means run , bottom black is x intercept which is 2.000 under rise is y-intercept and under the y axis is 0.000 and -4.000.
