Write the function that corresponds to the given situation.

D(x) = 70 (0.85)^x, A= 70, B= 0.85

Step-by-step explanation:

You start at 70, giving you your A value

Since it's decreasing, you subtract 0.15 from 1, leaving you with 0.85. That will be your B value.

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

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.
