Answer:
The sign of each y-coordinate changed.
Step-by-step explanation:
This was a reflection over the x-axis.
If you look at point F, it is (-5, -1) the corresponding point F' is (-5,1). Notice the numerical values of x and y are the same, but the sign of y flipped from negative to positive. The other four points all follow the same pattern.
A. The term "units" refers to the measurements in the original question or problem. When looking at the question, the units we are measuring are dollars/feet.
B. In this case, the f'(x) means we are looking for the cost (in dollars) to drill the next foot down.
C. Since the cost increases the more feet we drill down, the sign of f'(x) is positive.
The formula for tan is opposite/adjacent.
This being said, 12/13 would equal approximately 0.923077.
Hope this helps. ^^

Answer:
x=10
Step-by-step explanation:
Set up the equation, (3x+6)+54=90 because both angles equal up to 90 degrees, and then solve for x.
