Two functions f and g represent the profit of two companies, in millions of dollars, about 13 years after they went into business. Their observed profits for a small time period x are shown in the table. Which is the closest approximation of the time where the two companies have equal profit or loss? 13.253 years

7(x - 2) = 3(x + 4) solve the following equation. then enter your answer in the space provided using mixed number format.

Consider the proof. given: segment ab is parallel to line de. prove: what is the missing statement in step 5?

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.
