Agroup of scientists studied the effect of a chemical on various strains of bacteria. strain a started with 12000 cells and decreased at a constant rate of 4000 cells per hour after the chemical was applied. strain b started with 6000 cells and decreased at a constant rate of 3000 cells per hour after the chemical was applied. when will the strains have the same number of cells?

answer: sorry but i need points

step-by-step explanation:

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
