Problem Solve −4+4−6=12 − 4 j + 4 − 6 = 12 . Solution First we need to isolate the variable term by eliminating the denominator of the fraction. Multiply both sides by −6 − 6 . ( ( )−4+4−6=12( ) − 4 j + 4 − 6 = 12 ( ) ) −4+4= − 4 j + 4 = Next, subtract 4 4 from both sides. −4= − 4 j = Divide both sides by −4 − 4 . = j =

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.
