Answer:
y = 3, TU = 6
Step-by-step explanation:
SU is an angle bisector and divides the opposite side into segments that are proportional to the other 2 sides, that is
=
, substitute values
=
( cross- multiply )
14.4(4y - 2) = 48y
57.6y - 28.8 = 48y ( subtract 48y from both sides )
9.6y - 28.8 = 0 ( add 28.8 to both sides )
9.6y = 28.8 ( divide both sides by 9.6 )
y = 3
Then
TU = 2y = 2 × 3 = 6
Answer:
[-4, 2½]
Step-by-step explanation:
The quickest way to do this is to calculate how far apart each corresponding coordinate is, then take HALF of that range:
From -4 to -4 → 0
From 3 to -8 → 11
-3 + 5½ = 2½ [y-coordinate] → [-4, 2½]
** Just in case you were wondering why I did not calculate zero, zero is neutral, so it stays zero.
