A reasonable function is W = 7F + 5000
Where W is the weight of the plane and F is the number of gallons of fuel.
The domain is the set of possible values for F. That is from 0 (empty tank) to 400 (full tank).
So the domain is F = [0,400], or what is equivalente 0 ≤ F ≤ 400.
The range is the set of values of W.
The minimum value of W is when F = 0 => W = 7(0) + 5000 = 5,000.
The maximum value of W is when F = 400 => W = 7(400) + 5000 = 7,800
So the range is W = [5,000 ; 7,800], pr 5000 ≤ W ≤ 7,800.
you would factor using the perfect square method to get
(3m+5n)^2
Answer:

Step-by-step explanation:
<DAB = <B + <C
Answer:
110
Step-by-step explanation:
6 + 13x + 7x + 14 = 180
20x + 20 = 180
20x = 160
x = 8
Therefore, 6 + (13 * 8) = 110
