What is the least common multiple of the two denominators 6/8 , 4/32

Just tell me how to set up the equation.

What are the solutions of the system? solve by graphing. y = -x^2 -6x - 7 y = 2

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)
