Where is the following graph decreasing
f(x)=(c-6)(x+2)​

There were 816 people at a concert when a band started to play. after each song, only half the people stayed to hear the next song. how many people were left at the concert after x songs? write a function to represent this scenario.

Write the expression in simplified radical form. show all steps and work including any foil method work. (hint: use the conjugate. no decimal answers.) (9-2√3)/(12+√3)

Complete the solution of the equation. find the value of y when x equals to 28 x+3y=28
