Which is an equation of the line that is parallel to the x-axis and that passes through the point (5, 3)?
A. x = 5
B. y = 5
C. X= 3
D. y = 3

What is coefficient of the term of degree of degree 5 in the polynomial below

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.
