Two variables, x and y, vary inversely, and x=12 when y=4. what is the value of y when x=3?

Which function can be used to model the monthly profit for x trinkets produced? f(x) = –4(x – 50)(x – 250) f(x) = (x – 50)(x – 250) f(x) = 28(x + 50)(x + 250) f(x) = (x + 50)(x + 250)

Find the value of x in the diagram below. select the best answer from the choices provided
