In the year 2016, the total number of metric tons of copper produced in the world was 495,000.
Each year since, the total number of metric tons of
copper produced has increased on average by about
3.25% over the amount produced the previous year.
Which function models the total number of metric tons
of copper produced in the year that is x years since
2016?

Which value of m will create a system of parallel lines with no solution? y = mx - 6 8x - 4y = 12

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.
