In a particular country, railroad miles have been on the decline and the miles of roads in the highway system have been increasing. The function y=-1348.5x+145,081 represents the railroact
milles, while the function y=522.2x + 153,497 models the number of highway miles. For each function, x is the number of years after 1994.
a. Explain how the decrease in railroad miles can be verified by their given function while the increase in highway miles can be verified by their given function.
OA. The constant in the function representing the railroad miles is smaller than the constant in the function representing the highways miles, indicating that the railroad miles are decreasing a
the highway miles are increasing.
B. The slope of the function representing the railroad miles is smaller than the slope of the function representing the highways miles, indicating that the railroad miles are decreasing and the
highway miles are increasing.
OC. The function representing the railroad miles has a negative slope, indicating a decrease. The function representing the highway miles has a positive slope, indicating an increase.
b. Find the year in which it is estimated that the number of the country's railroad miles and the number of the country's highway miles were the same.
It is estimated that the number of railroad miles and the number of highway miles were the same during the year. (Round down to the nearest year.)
