(2a-1/3) / -8.25 / 15 when a= -2/5 and b= -8.25 Please answer as a simplified mixed number. Thank You!

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.

b. f(x) = –√x + 3this is the correct answer

all of the measures need to be converted to the same measure; such as inches. if you do that it is easy to determine which is the longest, 2500 mm which is approximately 97.5 inches.
