What is the slope of a line that is perpendicular to the line
y = -1/3x - 6

A.-1/3
B.-3
C.1/3
D.3

Factor this polynomial completely x^2-64

The distributive property allows you to say that 3(x − 1) = 3x −

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.
