He solution to the system of equation below is (−2, −1).
2x − 3y = −1
11x − 9y = −13
when the first equation is multiplied by −3, the sum of the two equations is equivalent to 5x = −10.
which system of equations will also have a solution of (−2, −1)?

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.
