Make a number line and show all values of x such that x≤1 2/3 and x<− 3/4

x < -¾

Step-by-step explanation:

And is intersection

x < -¾

x ≤ 1⅔

Intersection is the common region which is

x < -¾

Make a number line with open circle at -¾ and going towards left of -¾

  q

step-by-step explanation:

each line from a vertex to the midpoint of the opposite side is called a median. the point where the medians intersect, point q, is the centroid.

the centroid of δabc is point q.
