Can you me get this done it’s due tomorrow!

Hi  , the answer is 280-140/ 4-2 = 140/2  

y = 2/140 x

b .  70 beats each minute

Step-by-step explanation:  

we will  take a 2 point from the graph

(280,4) , (y1,x1)    and (140, 2) , (y2,x2)      each point represent a (y,x)  point

m = y1-y2 / x1-x2   = 280-140 / 4-2 = 140 /2

now , y/x = 140/2 ... by B. Multiplication we will get y = 2/140 x  

b .

from the graph we see that every minute  the curve increase 70 beats

Thanks

answer: idk

step-by-step explanation:

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.

happy to

pls mark as brainliest.
