If y varies directly as x, and y=4 when x=25, find y when x=275

Answer:

[tex]\fbox {y = 44}[/tex]

Step-by-step explanation:

Finding the constant of proportionality, k :

y = kx

4 = k(25)

k = 4/25

Now, substitute in the formula when x = 275 :

y = (4/25)(275)

y = 4(11)

y = 44

If you know the answer add it here!
