3pounds of bananas cost 1.5. what is the constant of proportionality that relates the cost in dollars ,y, to the number of pounds of bananas asap

$0.5

Step-by-step explanation:

formula ; y = kx

where ; y = $1.5

             x = 3 pounds of bananas

             k = constant of proportionality

Step 1. Do the equation based on the data given

y = kx

$1.5 = k3

Step 2. Compute the mathematical equation. Divide both sides by the coefficient of 3.

$1.5 = k3

  3      3

k = .5

Answer; $0.5 is the constant of proportionality cost in dollars per pound of banana.

0.25

Step-by-step explanation:

Have a nice day <3

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
