2x-4y+7=0 how do I find the slope for this?
Digiron [165]

Answer:

The slope is 1/2 and the y intercept is 7/4

Step-by-step explanation:

2x-4y+7=0

To find the slope, we need to put the equation in slope intercept form

y = mx+b

So we need to solve for y

Subtract 2x from each side

2x-2x-4y+7=0-2x

-4y +7 = -2x

Subtract -7

-4y+7-7 = -2x-7

-4y = -2x-7

Divide by -4

-4y/-4 = -2x/-4  -7/-4

y = 1/2 x +7/4

The slope is 1/2 and the y intercept is 7/4

tres hermanos danvueltas circuito en bicicleta. el mayor tarda 18 en dar Una vuelta el del medio 24 minutos yel menos 36 minutos
hodyreva [135]
Tienes que hallar el mínimo común múltiplo de las 3 cantidades.

18= 2×3²
24= 2³×3
36= 2²×3²

mcm(18,24,36) = 2³×3²=8×9= 72

Eso quier decir que si partieron a la misma hora se encontraran  de nuevo en el punto de partida 72 minutos después de la salida.

Las vueltas que habrán realizado será el resultado de dividir 72 entre el tiempo que tardan en dar una vuelta

<span>Mayor: </span>  = 4

<span>Mediano: </span>  = 3

<span>Pequeño: </span>  =  2

Soluciónes:

se vuelven a encontrar a los 72 min de la salida
<span>El mayor dió 4 vueltas, el mediano 3 y el pequeño 2</span>

ycow [4]
1 revolution: 360 degrees. 1 Hour= 60 minutes. 60x3000= 180000 ( number of revolutions per hour) 3600 seconds in a hour. 180000/ 3600 = 50 so therefore 60
