The population of bacteria in a petri dish doubles every 16 hours. The population of bacteria is initially 500 organisms. How long will it take for the population of the bacteria to reach 800? Round your answer to the nearest tenth of an hour,

The figure above shows the lengths of thesides of a rectangle in cm. find the valuesof x and y and then the area of the rectangle. sides: top= 3x - yleft= 3y + 4bottom= 2x + yright= 2x - 3 use both methods, elimination and substitution, if possible.

Graph the system: f(x)= 3/x-2; f(x)= 1/2x + 2

Find the quotient. 50a2 – 98b2 -5a +7b
