The telephone company made this table to show the number of telephones in the homes they surveyed:
Phones in home o 1 2 34 or more
Number of homes7|33 56 42
If these homes are representative of the community of 100,000 homes that the
company serves, about how many homes would you predict have 4 or more
12
telephones?

Write an equation for the function that includes the points (1,4/5) and (2,2/3)

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.

David estimated he had about 20 fish in his pond. a year later, there were about 1.5 times as many fish. the year after that, the number of fish increased by a factor of 1.5 again. the number of fish is modeled by f(x)=20(1.5)^x. create a question you could ask that could be answered only by graphing or using a logarithm.
