From the definition of a function, a function associates every element of the domain to a unique element in the codomain.
In other words, if two elements are equal in the domain, then their images should also be equal.
Since, x represents the number of cars, we consider the universal set as N, the set of all natural numbers.
Let x, y ∈ N and x = y
Then, 0.75x = 0.75y
⇒ f(x) = f(y)
Therefore, images are equal, whenever elements are equal.
Hence, the function f(x) = 0.75x is a function. Also, note that the domain of the function is the set of all natural numbers and the range is the set of real numbers.
:Two Angles are Supplementary when they add up to 180 degrees. Notice that together they make a straight angle.
and if that doesn't help
:There are in an angle of one fifth of the supplementary angle. Supplementary angle decides the angle to always be and the complementary angle is always (i.e., right angle)
It would be 50,000, because 5*10,000=50,000.
Answer:
The interest is $35 so it ends up costing her $70
Step-by-step explanation:
15/60 simplified is 1/4
1/4 is not equal to 3/4
