A train travels between two cities. The time the trip takes is inversely proportional to the average speed of the train. The trip takes 7 hours
at an average speed of 50 miles per hour. How long would the trip
take if the average speed is 70 miles per hour?

Options
A.27hr
B.9.8hr
C.6.3hr
D.5hr

3.76%

step-by-step explanation:

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

answer: he is 272195

step-by-step explanation: all you have to do is multiple 3535 and 77 and it equals 272195
