Ok so for this one i have to write an equation, solution, and answer. two groups hikers start at the same time at the same average speed. marks group hikes for 2.5 hours. sally’s group hikes for 4.7 hours and covers another 7.7 miles. how fast are the hikers going? equation: solution:

Colby and jaquan are growing bacteria in an experiment in a laboratory. colby starts with 50 bacteria in his culture and the number of bacteria doubles every 2 hours. jaquan starts with 80 of a different type of bacteria that doubles every 3 hours. let x equal number of days. colbys experiment follows the model: a.) y=50*2^x b.) y=50*2^8x c.) y=50*2^12x jaquans experiment follows the model: a.)80*2^x b.)80*2^8x c.)80*2^12x

If a || b and e || f , what if the value of y ?
