Three friends use a groupon and rent an airbnb at $30 a night. they pay $10 each and go up to their rooms. the owner realized he charged too much and it was only supposed to be $25. he sends his kid to the house with $5. each of the people keeps $1 and they give the kid $2 as they can't share it. so now each person has paid $9 for the room (total $27) and the kid has $2 total of $29.

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

answer:

f(5/2) = 10/3

i hope this you!

b.my answer is b.

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
