Answer:
(4.75, 2.25)
Step-by-step explanation:
Given the coordinate (x,y). If this coordinate is reflected over the x axis, the resulting coordinate will be (x, -y)
Note that the y coordinate was negated.
Let the original point needed be (x, y)
If the new point is located at (4.75, -2.25)
Since the y coordinate was negated, then;
-y = -2.25
y = 2.25
x = 4,75 (x coordinate remains the same)
Hence the original point is (4.75, 2.25)
Just divide 121 by 11 to get your answer.
The answer is a. Because at approximately 17 weeks the two lines meet.
The speed is the ratio between the distance and the time:

Data:
d=6343miles
t=9h

Then, the plane traveled at a speed of 704.77 miles per hour.
First, we need to find his unit rate, the amount he earns in 1 hour.
So, we have to divide 28.50 by 2.
That is:
28.50 / 2 = $14.25 per hour
To find the amount he earns in 8 hours, we will need to multiply hourly rate found by "8". So,
14.25 * 8 = $114
