Using the segment addition postulate, which is true?
1 answer:
The complete question is
"Using the segment addition postulate, which is true?
AB + BC = AD
AB + BC = CD
BC + CD = AD
BC + CD = BD"
Using the segment addition postulate, the true option is D; BC + CD = BD.
<h3>What is a line segment?</h3>A line segment is a straight line with finite length, and thus, have to endpoints(points on either ends).
We have been given the number line and four points A, B, C, and D on the line with coordinates -6, -1, 2, and 8 respectively.
(a) L.H.S. = AB + BC = 5 + 3 = 8,
R.H.S = AD = 14 ≠ 8.
So, this option is incorrect.
(b) L.H.S. = AB + BC = 5 + 3 = 8,
R.H.S = CD = 6 ≠ 8.
So, this option is incorrect.
(c) L.H.S. = BC + CD = 3 + 6 = 9,
R.H.S = AD = 14 ≠ 9.
So, this option is incorrect.
(d) L.H.S. = BC + CD = 3 + 6 = 9,
R.H.S = BD = 9.
So, this option is correct.
Hence, the correct option is (d).

<h3>What is a Proportional Graph?</h3>The constant of proportionality, k, of a proportional graph is given as, y/x. The graph is expressed by the equation, y = kx.
The equation given, M = 3n, represents a proportional relationship where k = 3.
Using a point on graph C, (400, 1,200):
k = 1,200/400
k = 3
Therefore, the graph that corresponds to the situation is: C.
