Answer:
d) 2 1/2
Step-by-step explanation:
if you make 5/2 a mixed number, you get 2 1/2
Answer:
Step-by-step explanation:
The formula for this is the one we use when we are given the ratio the directed line segment is separated into as opposed to the point being, say, one-third of the way from one point to another. The 2 equations we use to find the x and y coordinates of this separating point are:
and
where x1, x2, y1, y2 come from the coordinates of A and B, and a = 1 (from the ratio) and b = 2 (from the ratio). Filling in for x first:
and then y:

The coordinates of point E, then, are (0, 1).
Answer:
y = 1/2x represents a direct variation because it represents the direct variation formula: y = kx. In this case, the "k" is 1/2.
