Using proportions, it is found that the interval for the number of times Elliot must visit his parents is [14, 41].
---------------------
- The interval is found using proportions, by a rule of three.
- In each visit to his parents, Elliot flies 350 miles.
- To qualify for Gold status, he must fly at least 4900 miles. How many trips are this:
1 trip - 350 miles
x trips - 4900 miles
Applying cross multiplication:
He must visit his parents at least 14 times.
---------------------
- Also less than 14700 miles, how many trips are this?
1 trip - 350 miles
x trips - 14700 miles
Less than 42 trips, thus at most 41 times.
The interval is [14, 41].

Answer:
x=3 x=-3
Step-by-step explanation:
x^2-2x-4=-2x+5
Add 2x to each side
x^2-2x+2x-4=-2x+2x+5
x^2 -4 =5
Subtract 5 from each side
x^2 -4-5 = 5-5
x^2 -9 =0
This is the difference of squares
(x-3) (x+3) =0
Using the zero product property
x-3 =0 x+3 =0
x=3 x=-3
