At the movie theater, the total value of tickets sold was $2,727.50. Adult tickets sold for $10 each and senior/child tickets sold for $7.50 each. The number of senior/child tickets sold was 23 less than twice the number of adult tickets sold. How many senior/child tickets and how many adult tickets were sold?

Is δ pmr similar to δ smn ? if so, which postulate or theorem proves these two triangles are similar?

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.

The graph of f(x) = |x| is transformed to g(x) = |x + 11| - 7. on which interval is the function decreasing?
