The function f(x) = 5 1/5is reflected over the y-axis. Which equations represent the reflected function? Select two options. f(x) =1/5 (5)-x
f(x) = 1/5 1/5 (1/5 )x
f(x) = 5 1/5 (5)-x
f(x) = 5(5)x
f(x) = 5(5)–x

Planet earth has a mass of 5.9726x10²⁴ kg.then: 5.9726x10²⁴ kg=100% of the total earth mass.if the water´s mass=5x10-4 % of the total mass, we can solve this problem by the rule of three.5.9726x10²⁴ %*10⁻⁴ %x=(5.9726x10²³ kg)(5*10⁻⁴  %) / 100 %=2.9863x10¹⁹ kganswer:   the mass of the planet´s water would be   2.9863 x 10¹⁹ kg.
