A rule for estimating the number of board feet of lumber that can be cut from a log depends on the diameter of the log. To find the 2 d-4 diameter, d, required to get 5 board feet of lumber, the equation 4 = 25 is used. Solve this equation for d. Are both answers reasonable? O A. {24, – 16}; No, only 24 feet is a reasonable answer. O B. {20, – 20}; No, only 20 feet is a reasonable answer. O C. {9, - 20}; No, only 9 feet is a reasonable answer. O D. {16, - 24}; No, only 16 feet is a reasonable answer.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
