Every time that she stopped, the value of the speed is 0, the speed limit is the maximum represented in the graph and when she travels at this speed for a while the graph is a horizontal line.
So she starts at 0, then increases her speed until a limit then she drives at this speed for a while which is represented by a horizontal line. then, she has to slow to a stop, which means she goes back to 0, later increases her speed until the limit, drives a while until she finds a stop sign, represented by a horizontal line, and then goes to 0.
In conclusion, the graph that represents the journy is the fourth graph.
Step-by-step explanation:
use -4y for x in the second equation
-4 y + 5 y = 2
so
y = 2
then x = -4(2) = -8
(-8 , 2)

The ratio is 3/4. One foot is equal to 12 inches, 4 foot is equal to 4*12=48 inches. Therefore, the ratio of 36 in. to 4 ft = 36/48, which can be simplified to 3/4 (dividing both the numerator and denominator by 12).
