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.
There’s no picture or anything.
Answer:
slope = -2
Step-by-step explanation:
rise/run: y2-y1/x2-x1 .
=12-18/4-1 = -6/3 = -2
Answer:
<em>The correct answer is: False</em>
Step-by-step explanation:
<u>If the sum of the opposite angles in a quadrilateral is 180°</u>, then a circle can be circumscribed about the quadrilateral.
Here,
but,
So, a circle can't be circumscribed about the given quadrilateral.
Hey there!
So the original profit is y=22x; x=number of necklaces and y=profit
New:
y=29x; x=number of necklaces and y=profit
Xavier will earn $7 more if he switches to his new plan because a keyword in the question is "How many more" and that usually means to subtract, so take away 22 from 29 and you get 7
Hope this helps!
