Durante una semana el precio de ciertas acciones cambio de la siguiente manera: el lunes subieron $120, el martes bajaron $240, el miércoles subieron $100, el jueves bajaron $80 ¿Cuál fue el cambio total en el precio de las acciones en esa semana?

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides

alright so i think for this one it would to draw it out. this may be hard for me to try and draw, but i will do my best on here:

        r

  /       |     \

notice how it forms 2 triangles inside one bigger triangle.

so if we know the angle spr is the same as psr that is saying the measure of angle p is the same as angle s. this means the big triangle psr is either isosceles or equilateral. in both cases, the triangle is perfectly symmetrical when split down the middle, which is in this case rq. because we know it is perfectly symmetrical on both sides, we know that the two triangles inside the bigger one are equal.

i would think "anyone would want the best for their child" is correct

the first domain and range set to the left is matched with the top relation, and the second set the set in the middle goes with the bottom relation.
