you score an 86 on the first two exams. write and solve an equation to find the score x that you need on the second exam to have a mean of a score

Ineed ! the person who answers and shows their work on they got the answer first will be marked the !

Acolony contains 1500 bacteria. the population increases at a rate of 115% each hour. if x represents the number of hours elapsed, which function represents the scenario? f(x) = 1500(1.15)" f(x) = 1500(115) f(x) = 1500(2.15) f(x) = 1500(215)

Rewrite the following quadratic functions in intercept or factored form. show your work. f(x) = 3x^2 - 12
