Barry wants to buy a house. He is thinking a 15 year mortgage. The bank advertises an interest rate of 5% and Barry can afford a monthly payment of $1200. Using the formula P=1200[1−(1+0.0512)−12⋅15]0.0512, approximate the value of a house Barry can afford.

Do not round until the very end.

Round to the nearest dollar.

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.
