The solution to the system of equation below is (−2, −1).2x  − 3y  = −1  11x  − 9y  = −13when the first equation is multiplied by −3, the sum of the two equations is equivalent to 5x  = −10.

What is the difference between the predicted value and the actual value

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.
