i only got this far!! im so sorry!!
The reflected coordinates are (7,4) You can find this out by imagining a point on the left upper side in quadrant 2. Then, when you flip it to quadrant 1, both coordinates are positive!

Answer:
x = 14 is an extraneous solution
Step-by-step explanation:

Divide both sides by 4.

Square both sides.



Since we squared both sides, we much check for extraneous solutions because the process of squaring both sides can introduce extraneous solutions.
Check x = 14:





16 = -16 is a false statement, so the solution we found, x = 14, is an extraneous solution.
Answer: 250 hamburgers
Step-by-step explanation: x= hamburgers
If there are 72 more cheeseburgers than hamburgers there are:
x+72
The number of cheeseburgers and hamburgers=572 so:
572= x+72+x
Then solve
572=x+72+x
572=2x+72
-72 -72

500=2x
500/2=2x/2
250=x
