Answer: number of kids(k)=200
sand the number of adults(a)=300, visited the carnival.
The tool I used is called simultaneous equation and I used elimation method as the method.

Answer: Choice C </h3>
The open circle means we do not include the endpoint, hence the use of a greater than symbol. If we were to include the endpoint, then we'd have greater than or equal to. We can rule out choice B due to this reasoning.
The ray pointing to the right indicates we are talking about x values larger than 5, so we can rule out choice A and conclude the answer is C.
Side note: The notation is saying "x is a real number"
Answer
A.CD
Cause theCD is the mid point of triangle ADB which divides triangle in two half if you look carefully you can understand the diagram ☺️☺️

Step-by-step explanation:
Recall that
and that
Also note that,
and that
Now, to find the relative extrema of the function, we first have to compute the derivative of f(x) and find the values of x where the derivative is equal to zero, using the last equations, the linear property of the derivative and the product rule, we get that
Since for all x, to find the relative extrema of the function in the interval -4≤x≤4, we only have to find the values x, in the given interval, where . After a inspection of on the given interval, we can see that the extrema of f(x) can be find at .
It holds that
and that
