I speak spanish sorry for my english but this is the question: a, b and c are three vectors not null and not parallel each other, such that their initial points coincide and their endpoints are collinear. If xa + yb + zc = 0, determine x + y + z. a)4 b)3 c)2 d)1 e)0

OpenStudy (anonymous):

x, y y z son escalares por lo que veo.

OpenStudy (anonymous):

Si sus punto finales son colineares, entonces los tres están contenidos en un mismo plano.

OpenStudy (anonymous):

Bueno, si los vectores son colineares, entonces no son linealmente independientes, es decir, existen escalares x,y y z diferentes de 0 tal que se cumpla la ecuación de dependencia lineal que tienes ahi.

OpenStudy (anonymous):

Mmm pero eso no resuelve nada =/

OpenStudy (anonymous):

Lo siento amigo no se me ocurre nada. Hazme saber si lo puedes solucionar.

OpenStudy (anonymous):

Yo creo que la clave está en que tienen un punto en común. Pero no logro trasladarlo a una ecuación o algo matemático.

OpenStudy (anonymous):

ok bueno gracias igual seguire intentando
