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.
====================
B. because the slope is negative 5 so it can't be a or d. the y-interept can't be one because it is 11.
I got: 27/9 is the answer
Answer: That would be demonstrated as 3/14, or 3 over 14
Step-by-step explanation:
The numerator is the number being divided, and the denominator is the divider. So if I were to write 1/2, 1 is being divided by 2, which results with .50. .50 is half of the whole number 1, make sense? :)
Answer:
the "b" term is the term "-5 x" in the final quadratic expression
Step-by-step explanation:
Normally the "b" is the "linear term" in a quadratic equation.
So, perform the product of binomials and combine like terms to identify the final "b" term of the quadratic expression you get:
Therefore the "b" term is the term "-5 x" in the final quadratic expression.
