What is the general form of the equation of a circle with center at (a, b) and radius of length m? . a. x2 + y2 − 2ax − 2by + (a2 + b2 − m2) = 0 . b. x2 + y2 + 2ax + 2by + (a2 + b2 − m2) = 0. c. x2 + y2 − 2ax − 2by + (a + b − m2) = 0. d. x2 + y2 + 2ax + 2by + a2 + b2 = -m2.

Marcus and cody both leave the park at the same time, but in opposite directions. if cody travels 6 mph faster than marcus and after 4 hours they are 64 miles apart, how fast is each traveling? solve using rare times time = distance.

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.

X/y + 4y/x divided by x/y - 2y/x explain as in depth as you can how you simplfied the fractions. i don't know where to start on this : /
