A colony of bacteria triples in population every 24 hours. There were 20 bacteria
initially. The variable y gives the number
of bacteria after x days. What is the
coefficient, a, for the exponential equation
of the form y=a. b' that describes the
situation?

yeah. here's some.

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

answer: 5100 just subtract
