. Point P is the midpoint of . Point Q is the midpoint of . Point R is the midpoint of . Point S is the midpoint of . is an invalid relation.
Because point R is the midpoint of and point S is the midpoint of , we can conclude that .

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 !

answer: group b.

step-by-step explanation:

x= cost per bracelet

number of bracelets * x + shipping charge = total cost
