G(5) = (3/10) - (5/2)
g(5) = (3/10) - (25/10)
g(5) = -22/10
g(5) = -2 1/5
Answer:
The answer should be 54, lmk if it works
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:
Fractions that have the same denominator.
17. c You plug in (1,1) and it works
18. d You find all the possible x and y values and see if they fit in with the answers
19. slope = 4/3 y-intercept = -3 m is 4/3 and b = -3 tells us slope and y-i
