Answer:
D (the last one)
Step-by-step explanation:
because the line on the outside of the numbers means they're absolute.
the absolute is how far they are from zero no matter if they are negative or positive.
The value of xy is 114 which is a real number.
real numbers are all numbers/points that exist at the variety line.real numbers may be divided into the following divisions:Rational numbers; any range which may be written within the form ofin which p and q are co-prime integer numbers , are called rational numbers. Irrational numbers ; all numbers which cannot be written as a simple fraction is referred to as irrational numbers.
Given two real numbers x and y . Let us consider
.
According to the question their sum is 25.
.............(i)
The difference of the numbers is 13.
...........(ii)
Now we have to solve the simultaneous equation:
adding equations (i) and (ii) we get:

Substituting the value x=19 into equation (i) we get:

Now let us find the product xy

The product xy is 114 which is also a real number.

assuming you mean

remember
in form

a is leading coficient
(h,k) is vertex
k will be the minimum or max value of the function
if a is positive, then the parabola opens up and k is minimum
if a is negative, then the parabola opens down and k is max
given
a is negative
the parabola opens down and k is the max value
it is -3
the max value is -3, which occors at x=2
g(2)=-3 is max
Wholes, integers, rationals, reals
