B. Two end points
A regular line has an undefined length while a segment is defined by 2 points.
Answer:
a)
<u>Verify is the corresponding sides have same ratio:</u>
- AB / DE = 50/60 = 5/6
- BC / EF = 20/24 = 5/6
Since the ratios are same, the triangles are similar
b)
<u>If one dimension is same, the base areas will make difference by the square of the scale factor:</u>
Distance from finish line can be computed by subtracting the amount he has ran from 3. Every minute he runs .5km, and we can use this to create a function to describe this instance.

The distance remaining is equivalent to the minutes multiplied by .5km for each minute subtracted from 3 which is the total distance.
Answer:
It will help with finding all of the terms for the polynomial.
Step-by-step explanation:
it should be correct.
Answer: y varies directly as x ", " y varies proportionally as x ", or " y is directly proportional to x . ") This means that as x increases, y increases and as x decreases, y decreases—and that the ratio between them always stays the same.
