F(x) = |x + 2| - 3
0 = |x + 2| - 3
0 = x + 2 - 3
0 = x - 1
+ 1 + 1
1 = x
Domain: x > 1 and x < 1
Solution Set of the Domain: {x| 1 > x > 1} and {x|x 1 < x < 1} or (1, 1)
f(x) = |x + 2| - 3
f(x) = |0 + 2| - 3
f(x) = |2| - 3
f(x) = 2 - 3
f(x) = -1
Range: x ≤ 3
Solution Set of the Range: {x|x ≤ 3} or (-∞, 3]
Parallel lines mean that the slopes are the same, while perpendicular means that the slopes are negative reciprocals from each other.
With this information,
1. The slopes are the same, so PARALLEL.
2. The slopes are negative reciprocals, so PERPENDICULAR.
3. Same as the second.
1: 10x17=170
2:10x80=180
3:36 hours each day getting cars on and off 25 days so 36x25=900
4:49x34=1,666+52x3=156 the total is 1,822 dollars
Is there more to this question because it’s missing the information.
█ Explanation <span>█
Let's call the missing altitude 'x'.
</span><span>✦ To find the plane's altitude, find the tan of 30 degrees. The side opposite is going to be x, while the side adjacent is going to be 4.4 miles.

Answer: 2.54 * 5280 ~ <span>
13,400 ft
