Find x value for the point that splits segment cd in half if point c is located at (−2, 4) and point d is located at (3, 7).

The x value is 1/2, or 0.5

Just use the midpoint formula
(x2+x1)/2 , (y2+y1)/2

to find the midpoint. The x value would be (x2+x1)/2, so plug in the numbers.
(-2+3)/2 = 1/2

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
