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=-1250.2x + 142,602 represents the railrond miles, while the function y=501.5x + 158,449 models the number of highway miles. For each function, x is the number of years after 1995

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 your)

1986

Step-by-step explanation:

Function that represents railroad miles

Function that represents number of highway miles

We have to find in which year (1995+x) the miles of railroad and highway is the same so

So, the year is

In the year 1986 the railroad and highway miles were equal.

It is estimated that the number of railroad miles and the number of highway miles were the same during the year 1986.

Given

The function y =-1250.2x + 142,602 represents the railrond miles.

While the function y =501.5x + 158,449 models the number of highway miles.

For each function, x is the number of years after 1995.

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.

Therefore,

Then,

1995 - 9 = 1986

It is estimated that the number of railroad miles and the number of highway miles were the same during the year 1986.
