Turn 3x - 4 = 2 into a model equation (dont have to solve it)

1. what is the measure of ∠abc? what is the measure of ∠abd?

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

Find the length of the normal and the angle it makes with the positive x-axis. (see pictured below)
