True or false, A function is a relation if and only if the x-values do not repeat in a given set

Answer:

the answer is the letter D

Final answer:

By rearranging the midpoint formula, it can be determined that the other endpoint of the line segment is (9, 13) (option D) when one endpoint is (1,3) and the midpoint is (5,8).

Explanation:

This question relates to coordinate geometry, a branch of mathematics. In coordinate geometry, the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) is determined by the mean of the x-coordinates and y-coordinates, meaning the midpoint (xm, ym) is given by ((x1+x2)/2, (y1+y2)/2). If you have one endpoint ((x1, y1) which is (1,3) in this case) and the midpoint (xm, ym which is (5,8) in this question), you can solve for the unknown endpoint (x2, y2) by rearranging the midpoint formula to x2 = 2*xm - x1 and y2 = 2*ym - y1. Substituting the given coordinates into the formulas, we find that x2 = 2*5 - 1 = 9 and y2 = 2*8 - 3 = 13. Therefore, the other endpoint of the line segment is (9,13), hence option D is the correct answer.

Answer:

u would add 488+488 so it = 976

Step-by-step explanation:

Answer:

LCM=120

Step-by-step explanation:

A=2^3 x 3 x 5^2

2^3= 2 x 2 x 2 = 8

5^2= 5 x 5 = 25

8 x 3 x 5 = 120

A= 120

B=2^3 x 5

2^3= 2 x 2 x 2 = 8

8 x 5 = 40
