Answer:

(3,3)

x=3 and y=3

Step-by-step explanation:

The system of equations are:-

3x - y = 6

6x + y = 21

Elimination method: To eliminate one variable by add/sub both equation and solve for another variable.

3x - y = 6

6x + y = 21

Add both equation and eliminate y

3x + 6x = 6 + 21

       9x = 27

          x = 3

Put x=3 into 6x + y = 21

6(3) + y = 21

18 + y = 21

      y = 21 - 18

      y = 3

Hence, The solution of the system of equations is (3,3)

Answer:

<em>y = 4x - 57 </em>

Step-by-step explanation:

( x_{1} , y_{1} )

( x_{2} , y_{2} )

m = \frac{y_{2} -y_{1} }{x_{2} -x_{1} }

y - y_{1} = m ( x - x_{1} )

~~~~~~~~~~~~~~~

( 15 , 3 )

( 19 , 19 )

m = \frac{19-3}{19-15} = 4

y - 3 = 4 ( x - 15 )

<em>y = 4x - 57</em>

30. Felipe va a hacer un banderín para su equipo de fútbol, con las medidas que se indican en la figura. ¿Cuánta tela ocupará pa
blagie [28]

Veremos que el area del banderín es 930cm^2, entonces la opción correcta es A.

<h3>¿Que area tiene el banderin?</h3>

Luego de una pequeña busqueda online, pude ver que el banderin es un triangulo isósceles con base de 31cm y altura de 60 cm.

Recordar que para un triangulo de base b y altura h, el area es:

A = b*h/2

Entonces el area del banderín va a ser:

A = (31cm)*(60cm)/2 = 930cm^2

Entonces la opción correcta es A.
