Answer:
10/3
Step-by-step explanation:
SO we have the function [tex]f(x) = -\frac{2}{3} x +5[/tex]
We have to find f(5/2) or f(2.5)
Notice the similarity between f(5/2) and f(x)
f(5/2) basically means substitute 5/2 for x
So al we have to do is substitute [tex]-\frac{2}{3}x+5\\ as \\ -\frac{2}{3} *\frac{5}{2} +5\\[/tex]
So we get:
[tex]-\frac{10}{6}+5\\=-\frac{5}{3} +5\\\\=\frac{-5+15}{3} =\frac{10}{3}[/tex]
