Does anyone know this i’ve been stuck on it because i can’t explain it DONT ANSWER IF TOU DONT KNOW!! you will be reported

Yes, There is a proportional relationship

Step-by-step explanation:

I know this because both numbers are even and end in 0's. 50 x 4 = 200.

The 50 starts at the origin (0,0) which is (x,y) so imagine a graph and do that or just draw a graph because it is more work but it is easier in the end. So there is a proportional relationship.

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!
