In which choice is y a nonlinear function of x? O A. y = x/4 + 5
O B. y = 10 + x
O C. y = x+3/4 - 2x
D. y = 2 /x-3 + 5

Option D

Step-by-step explanation:

For a function to be linear, the index of x should be 1. In D the coefficient of x is -1. Therefore D cannot be linear

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2

step-by-step explanation:

i agree because i see the other persons thinking is clear
