20,112.5 meters
Multiply the length of the track by 10, then multiply that number by 5
Im not sure about equation 1 because theres a 3 after the y and i dont know if that was an error but if it was and its actually meant to read : y=2x+1 then equation 1 &2 are both linear functions.
The answer is C because. 4,000,000 is closest to <span>3,794,100</span>
Y=-1/3-2 because you have to make the slope into a negative inverse and the y-intercept stays the same because it's perpendicular.
Normal:3
Negative inverse: -1/3
4/6, 12/15, 8/12 are some of the expressions
