A submarine is 20 meters below sea level. The submarine is descending 15 meters every minute. After 2 hours, what is the submarine's elevation?

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

it has the same slope and a different y-intercept

hope this : )

answer: what do you mean

1/2(2*4)=6 $$- agahajakanajak
