How do you solve this by completing the square? 6x^2-10x+4=0 i got 3x-5/2=+or-√17/2. i'm not sure.

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.

Check all that apply. f is a function. f is a one-to-one function. c is a function. c is a one-to-one function.

3x + 4y = 5 x- 3y = -7 solve by substitution
