Determine the value of k that partitions a segment into a ratio of 1: 4.
1 answer:
Given the points A(-1<span>, 2) and B(7, 8), </span>determine<span> the coordinates of point P on directed line </span>segment<span> that </span>partitions<span> in the </span><span>ratio 1</span>/3<span>. Solution: Method </span>1<span>: A </span>1/3 ratio<span> divides the </span>segment into 1<span> + 3 = </span>4<span> equal parts. The direction is from A to B, so use the </span>ratio k<span> from A/P which is </span>1/4<span> of the line </span>segment<span>. Hope this helps

The answers are marked in the attached image. The associative property of addition states that we can group numbers in any order we want as long as we're adding them. The same applies for the associative property of multiplication.
A similar rule is the commutative property of multiplication which says we can multiply numbers in any order. Example: 2*3 is the same as 3*2. Addition works this way as well. Example: 5+7 is the same as 7+5
