What is the equation of the exponential regression equation? Round all
numbers in your answer to three decimal places.

A. 7 = 10,5797,355*
B. y = 7,355 •0,998*
O
C. y = 7,355 10,579*
O D. y = 10.579.0.998*

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.
