Point A is at -2 and point B is at 5. А

Which shows how to determine the point that will divide the segment into a 4:5 ratio using the formula x = (a + b)
(x2 - x) + xy?
O x= [0](5 + 2)-2
x = ()(5 + 2) - 2
O x=()(5 – 2) + 2
Ox=
ox=14/15 - 21+2

If m∠abc = 70°, what is m∠abd? justify your reasoning.  using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°.  using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°.  using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality.  using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
