Step-by-step explanation:
Suppose that the weight (in pounds) of an airplane is a linear function of the amount of fuel (in gallons) in its tank. When carrying 15 gallons of fuel, the airplane weighs 2187 pounds. When carrying 35 gallons of fuel, it weighs 2303 pounds. How much does the airplane weigh if it is carrying 50 gallons of fuel?
----
You have two points relating fuel and weight.
(15,2187) and (35,2303)
------------
slope = (2303-2187)/(35-15) = 5.8
----
intercept = ?
2187 = 5.8*15 + b
b = 2100
-------
Equation:
f(x) = 5.8x + 2100
---
f(50) = 2390 lbs.

Answer:
Breadth or width = 4
Step-by-step explanation:
Givens
Area = 200 cm^2
L = 50 cm
w = ?
Formula
A = L*w
Solution
200 = 50 * w Divide by 50
200 / 50 = w
w = 4
For infinitely many solutions, you must get each side of the equation to equal itself. So solve the first equation: 7 - 5 + 3x - 1
2 + 3x - 1
1 + 3x
Now make the blanks 3x and 1. For no solution, you can have anything other than x = an integer or x itself. If x = 2 + x, then it will have no solution. We have the solved equation: 1 + 3x. Fill in the blanks with 3x + any integer other than 1. For one solution, make it so x equals an integer. For example, you could fill in the blanks with 2x + 4, or anything other than 3x + 1 or 3x + any integer other than 1.
