Marissa researched the cost to have custom t-shirts printed by several local and online vendors. she found that each store’s charge for the job could be modeled by a linear function that combined a flat charge for artwork with a per t-shirt rate. marissa plotted the functions on a coordinate grid and found that two of the functions produced lines that had the same y-intercept. how should marissa interpret this result? a. those two vendors charge the same rate per shirt. b. those two vendors charge the same flat rate for artwork. c. those two vendors will have the same total cost to produce one shirt. d. those two vendors will charge the same total cost for any size job.

The correct answer is B. Those two vendors charge the same flat rate for artwork.

This is because the slope represents the rate of change of the function, or the rate per shirt, in this case. The y-intercept represents the flat rate for artwork, which can also be modeled as the cost of "0" shirts. This is the starting cost that will then be added to the rate that will change according to the number of t-shirts you buy.

Despite the same y-intercept, the total cost can change if the slope is different (this represents the rate per t-shirt) even if the same number of shirts are ordered (this eliminates options C and D).

Hope this helps!

answer: when you burn wood, the carbon reacts with the oxygen in the air to create ash and smoke. that is a permanent change you cannot undo that.

step-by-step explanation:

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.
