Consider the line y=−7x+5 . find the equation of the line that is parallel to this line and passes through the point , −8 5 . find the equation of the line that is perpendicular to this line and passes through the point , −8 5 .

Parallel lines have equal slope do slope of 2nd line is -7 also. using point slope we get y-5=-7(x+8). solve for to get. slope intercept y=*-7x-51

perpendicular lines have slopes that are negative reciprocals do slope of this line is 1/7. using the above processes we get y,-5=1/7(x+8) or y=1/7x +43/7

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.

2160ft^3 i think you could use a formala to you out with this in the future
