C ; x must be greater than or equal to 52 because you have to be 52 inches or greater to ride this ride.
Step-by-step explanation:
=-32-9 08 3X-97y
9- 2⋅ x+9- 7⋅ y+(1 0- 7⋅ x+3- 2)
If Andrew were to rest, he would not be moving (walking). During such a period, the beginning distance would be the same as the ending distance.
In this graph there are two such time intervals: BC and DE. Notice how the graph is 'flat' on each; this 'flat' graph indicates a speed of zero.
First equation simplifies to
y=(4/5)x-1
The second equation simplifies to
y=(4/5)x +1
So the answer is
No Solution
