Your teacher is giving a test that has 5 more four-point questions than six- point questions. The test is worth 120 points. Which system represents this information? (A) x +5=y; 4x + 6y=120 (B) x+y=5; 6x + 4y = 120 x-y=5; 6x + 4y= 120 (D) x-y=5; 4.x + 6y= 120​

Solve this system of equations. 12x − 18y = 27 4x − 6y = 10

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.
