Which of the following shows a positive nonlinear relationship? (assume values of x greater than 0) a. y equals 5 plus startroot x endroot b. y equals 5 plus 7.2 x c. y equals startfraction 86 over x endfraction d. y equals 86 minus 6.6 x click to select your answer.

A and C represent positive nonlinear relationships

Step-by-step explanation:

We assume that x≥0

A. Since √x is positive and nonlinear because the exponent of x is 1/2, then y=5+√x is always positive and is nonlinear.

C. Since x^-1= is a non linear relationship and x≥0 then y= is positive and nonlinear.

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour
