Answer:

(-7,3)

count from the origin point to where underneath point b is and you have x but since it's on the positive side and you're flipping it make it negative

then count up from that point and you have y, since you're on the positive top half it stays positive

Un escalador sube 225m de altura. El asenso lo hizo en 3 etapas. En la primera subio un quinto en la, en la tercera un cuarto. ¿

kiruha [24]

Answer:

Segunda etapa= 123.75 metros

Step-by-step explanation:

Altura total= 225 metros

<u>En la primera estapa subió el 20% (un quinto):</u>

Primera etapa= 225*0.2= 45 metros

<u>En la tercera etapa subió 25% (un cuarto):</u>

Tercera etapa= 225*0.250 56.25 metros

Ahora debemos determinar cuánto subió en la segunda etapa:

Segunda etapa= altura total - total subido

Segunda etapa= 225 - (45 + 56.25)

Segunda etapa= 123.75 metros

use the elimination method to solve the system of equations choose the correct ordered pair 7x+4y=39 2y+4y=14

Anvisha [2.4K]

$x = 5 \: and \: y = 1.$

Step-by-step explanation:

$7x + 4y = 39 \: - {eq}^{n} (1)$

$2x + 4y = 14 \: \: - {eq}^{n} (2)$

Multiply Equation no (1) with 2 and Equation no (2) with 7.

$14 x + 8y = 78.$

$14x + 28y = 98.$

$( - ) \: \: \: ( - ) \: \: \: ( - )$

$0x + -20y = - 20$

$- 20y = - 20$

$y = \frac{ - 20}{ - 20}$

$y = 1$

Substitute the value of "y" in Equation no (1)

$7x + 4y = 39.$

$7x + 4(1) = 39.$

$7x + 4 = 39.$

$7x = 39 - 4$

$7x = 35.$

$x = \frac{35}{7}$

$x = 5.$
