De cuantas formas se puedes sentar cuatro parejas de casados alrededor de una mesa circular si no debe haber dos mujeres juntas ni dos hombres juntos? no importa si las parejas quedan separadas

step-by-step explanation:

circumference divided by 3.141592654 then timesthe radius twice

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4

because that’s us why
