5-4(n+2)=18 


-4(n+2)=18-5
 

  Subtract \ 5 \ from  \ both \ sides
 

-4(n+2)=13

 

n+2= \dfrac{13}{-4}    Divide \ both \ sides \ by \ -4

<span>n+2= -\dfrac{13}{4}  
</span>
<span>n+2= -\dfrac{13}{4}-2    </span>Subtract \ 2 \ from \ both \ sides&#10;<span>
</span>
n=- \dfrac{21}{4}

Decimal \ Form: -5.25

La ecuación de la recta que lasa a través de los puntos P1 (2,5) y P2 (4,11) es: a) 3x+y+1=0 b)3x-y-1=0 c) 3x-y+1=0
Zolol [24]

Respuesta:

3x-y-1 = 0

Explicación paso a paso:

La forma estándar de ecuación de una línea se expresa como y = mx + b

M es la pendiente

b es la intersección con el eje y

Dada la coordenada P1 (2,5) y P2 (4,11)

Pendiente m = y2-y1 / x2-x1

m = 11-5 / 4-2

m = 6/2

m = 3

Sustituya m = 3 y (2,5) en y = mx + b

5 = 3 (2) + b

5 = 6 + b

b = 5-6

b = -1

Obtén la ecuación

y = 3x-1

Igualar a cero

y - 3x +1 = 0

Multiplicar por -1

3x-y-1 = 0

Esto da la ecuación requerida

The length of one of the sides of the larger pentagon is 24 cm. The length of one of the sides of the smaller pentagon is 8 cm.

24÷8=3

So, if the larger pentagon is 3x the size of the smaller pentagon, we can find the area of the smaller pentagon by dividing the area of the larger pentagon by 3.

135÷3=45

The area of the smaller pentagon is 45in²

2.2x+3y=15.25 <br>4.6x+2.1y=18.325<br>USING ELIMINATION<br>SHOW WORK PLEASE
Artist 52 [7]

-4.6(2.2x+3y=15.25) = -10.12x - 13.8y = -70.15

2.2(4.6x+2.1y=18.325) = 10.12x - 4.62y = 40.315

simplify

-4.62y = -29.835

divide both sides by -4.62 to isolate y

y= 6.46

2.2x + 3 (6.46) = 15.25

2.2x + 19.38 = 15.25

subtract 19.38 to both sides

2.2x = -4.3

divide 2.2 to both sides

x= -1.95

I hope that this helped :)
