At the beginning of the month, Evan had $24 in his account at the school bookstore. For each problem below, use a variable to represent the unknown amount in each equation you write. Remember, he he starting out with $24. 1.) First he bought some writing supplies that cost $16. Use "a", to represent his balance. *

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

Suppose y varies directly with x. write a direct variation equation that relates x and y. then find the value of y when x=12 y=7 when x=3

Which function has the domain x> -11? y= x+ 11 +5 y= x-11 +5 y= x+5 - 11 y= x+5 + 11
