When x = 500, y = 10
a)
Find a formula for y in terms ofx.
b)
Calculate the value of y when x=350​

Respuesta :

Answer:

a. y = x/50

b. 7

Step-by-step explanation:

Here, we have a direct proportional relationship

a) y = kx

where k is the proportionality constant

10 = k * 500

500k = 10

k =

10/500 = 1/50

The formula is;

y = x/50

b. when x = 350

y = 350/50

y = 7
