Write the co-efficent of x in -5/2xyz

The coefficient is simply -5/2.

An expression, in this case -5/2xyz, is made up of the coefficient and the variables. We can see that the only number that prefaces the variables is -5/2.

As a result, we can take away the variables and keep the number -5/2, which would be the coefficient.

Hope this helps.

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.
