The directions on a turkey tell you to cook the turkey 20 minutes per pound. Part A: Write a function in function notation for this situation where X is the number of pounds.
Part B: Describe the domain of this function. Assume turkeys can weigh up to 30 pounds.
Part C: Graph this function and state the range.
Part D: Use this graph to determine the cooking time for an 18 pound turkey.

Step-by-step explanation:

Let y be the time required to cook the turkey, and x the number of pounds of the turkey.

The time required, x, is equal to the turkey's weight (in lbs) times 20 min/lb.

y = 20(min/lb)x

The domain of this function is 0 - 30 pounds.

The cook time for an 18 lb turkey is y = (20min/lb)*(18 lb) = 360 min

25.2

step-by-step explanation:

2+4x6-8/10= 25.2

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
