You need to write the entire function: y = f(x) = 2x + 6.
Here the input quantity is x, and the output is y (or f(x)).
Answer:
Nitrogen
Step-by-step explanation:
Nitrogen and oxygen are by far the most common; dry air is composed of about 78% nitrogen (N2) and about 21% oxygen (O2). Argon, carbon dioxide (CO2), and many other gases are also present in much lower amounts; each makes up less than 1% of the atmosphere's mixture of gases. Hope this helped!
If you plug in 12 for x.
Your expression is y= 2(12)/3y
then you just solve for Y
Answer: The answer is 4 gallons
Step-by-step explanation: 4 gallons = 2 x (14 + 10) x 8 = 384 sq ft
windows = 2 x 2 x 5 = 20 sq ft
door = 4 x 7 = 28 sq ft
total = 384 - 20 - 28 = 336 sq ft.
336/350 is rounded up to 1 gallon
