Halle la ecuación del eje x y la ecuación del eje y, usando dos puntos que se encuentren sobre los mismos.
lisov135 [29]

Una linea recta ( cualquier eje coordenado es una línea recta) queda definida si se conocen dos puntos que están sobre ella.

Solución:

Ecuación del eje x      y = 0

Ecuación del eje y      x = 0

Para darle respuesta a la pregunta podemos seguir el siguiente procedimiento:

  • Escogemos dos puntos arbitrarios sobre el eje x, por ejemplo

P ( 2 ; 0 )  y Q ( 5 ; 0 )         ( todos los puntos sobre el eje x tienen coordenada y = 0.

Según la cual  m = (y₂ - y₁)/ ( x₂ - x₁ )    m = 0

  • Usamos la ecuación pendiente-Intercepto

y = m×x + b         donde m es la pendiente y b el intercepto con el eje y

y entonces tenemos:

  • m = 0    b ( 0 ; 0 )
  • Por sustitución en la ecuación pendiente-intercepto

y = 0

Procediendo de forma similar obtendremos la ecuación del eje y

P´( 0 ; 4 )     Q´( 0 : 8 ) entonces

y = m×x + b

En este caso, la pendiente no es definida ( tang 90° ) y b es de nuevo el punto b ( 0 ; 0).

A partir de  que todos y cada uno de los puntos sobre el eje y son  de valor 0 para x, concluímos que  ecuación del eje y es

x = 0

Kierran is trying to find the circumference of a circle. He knows that the radius (r) of the circle is 6 feet and that the diame
victus00 [196]

The formula should he use willl be 3.14(2). Option B is correct.

<h3 /><h3>What is the area?</h3>

The space filled by a flat form or the surface of an item is known as the area.

The number of unit squares that cover the surface of a closed-form is the figure's area. Square centimeters and other similar units are used to measure area.

Given data;

Radius,r = 6 feet

Diameter,d=2

Circumfererenc,C

The circumferrence of the circle is;

C=πD

C= 3.14 × 2

The formula should he use willl be 3.14(2).

Hence, option B is correct.

To learn more about the area, refer to the link;

3x − x − 1 = 15<br> What is x
azamat

Answer: x=8

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3x−x−1=15

3x+−x+−1=15

(3x+−x)+(−1)=15(Combine Like Terms)

2x+−1=15

2x−1=15

Step 2: Add 1 to both sides.

2x−1+1=15+1

2x=16

Step 3: Divide both sides by 2.

2x /2 = 16 /2

x=8

use the formula A=LW to find the length of a rectangle when the width is 29 yards and the are is 1,044 square yards. Help please
sukhopar [10]

Answer:

L = 36 yd

Step-by-step explanation:

Given the area of a rectangle of 1044 yd², and a width of 29 yards:

Using the formula for finding the area of a rectangle, A = L × W, algebraically solve for the length (L):

A = L × W

where:

A = area of a rectangle = 1044 yd²

L = length of a rectangle

W = width of a rectangle = 29 yd

<h3><u /></h3><h3><u>Solution:</u></h3>

Divide both sides by W to isolate L:

\displaystyle\mathsf{\frac{A}{W}\:=\:\frac{L\:\times\:W}{W}}

\displaystyle\mathsf{L\:=\frac{A}{W}}

Substitute the values for the area and the width of a rectangle:

\displaystyle\mathsf{L\:=\frac{1044\:yd^2}{29\:yd}}

L = 36 yd

Therefore, the <u>length</u> of a rectangle is 36 yards.
