Which equation can be used to find the answer? usman paints the entire length of a fence in a day. he paints the last 12 m of the 38 m fence in the afternoon. how many meters of the fence does he paint in the morning? a. f = 38 ÷ 2 f = 19 19 m b. f – 12 = 38 f = 50 50 m c. f = 12 · 2 f = 24 24 m d. f + 12 = 38 f = 26 26 m

The answer would have to be A

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.
