Rewrite the equation in Ax+By=C form

use integers for A, B, and C.

Y+5=2(x+4)

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.

The variables should add up to equal 1

These are the multiples of 15 but what you are probably asking or what are the factors of 15
