marta [7]

8 days—> because if you 160 insurance is already added, subtract that to get your original price since that’s what is actually being counted.
So I did 760-160=600
600/75=8
Also your answer is D.

Answer:

5x -7y = 21

Step-by-step explanation:

A sketch can convince you that BC is a transversal perpendicular to parallel lines AB and CD. The question asks for an equation for CD, so we just need to write the equation of a line through D that is parallel to AB.

One way to do this is to equate the slopes of the parallel lines:

∆y/∆x for AB = ∆y/∆x for CD

(y2 -y1)/(x2 -x1) = (y -2)/(x -7) . . . . . . where (x1, y1) = A; (x2, y2) = B; (7, 2) = D

(4 -(-1))/(1 -(-6)) = (y -2)/(x -7)

5(x -7) = 7(y -2) . . . . . . . . . . . . . cross multiply

5x -7y = 21 . . . . . . . . . . . . . . . . add 35 -7y, simplify

Note that the graph shows the line CD is named "b", and its equation is shown at upper left. Multiplying that equation by -1 gives the one shown here.
