Answer:
ok so this awnser is v7a
Step-by-step explanation:
An even function is a function where positive and negative values of x give you the same result.
Where f(2) = f(-2) and f(3) = f(-3)
To formally check it, you need to evaluate f(-x) and see if you get the original function back.
Graphically, an even function is symmetrical over the y-axis.
The only graph here that does all of that is f(x) = |x|
The equation would be 50 + 16x = 80 + 14x. The answer is 15 pints of oil.
The answer is 78.5 you can get this by multiplying pi by the radius which is 5 then square it and you get 78.5
