4 thumb drives and 1 CD have a total capacity of 18 gigabytes. 3 CDs and 4 thumb drives have a total capacity of 22 gigabytes. Find the capacity of 1 thumb drive and the capacity of 1 CD.

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.

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

$9.41

step-by-step explanation:

i think the correct option is the second option.
