0.7a−0.8b =−0.1 a−1.4 = −6(b−0.1) Consider the system of equations above. If (a, b) is the solution to the system, then what is the value of the sum of a and b?

Create a question with this scenario you could ask that could be answered only by graphing or using logarithm. 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.
