The cost for each car entering President George Bush Turnpike at Beltline road is $0.75. The equation that represents this relat
vesna_86 [32]

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.

Find a, d, e on a triangle.
DiKsa [7]

Answer:

A=20 degrees

D=70 degrees

E=110 degrees

Step-by-step explanation:

A=20 because a right angle always = 90 so 90-70=20

D=70 because I believe that angles C and D make a right angle, and C = 20 degrees, so we now subtract. 90-20=70

E=110 because D and E = a straight line, which is 180, and sense D is 70 degrees, all we need to do is subtract. 180-70 is 110, so our answer is 110

Hoped this helped, and let me know if I messed up somewhere.
