Answer:
Step-by-step explanation:
We are given with two equations
first equation is 
second equation is
we find the result of subtracting two equation
subtract the second equation from the first, so
first equation - second equation, multiply second equation by -1 and then add it with first equation
Now add both equations, we get
Answer:
Identity function
Step-by-step explanation:
We are given the following in the question:
Let f(x) be a function.
Then, inverse of f(x) can be written as:
The composition function of the function and the reverse function can be found as:
which is an identity function.
Thus, the correct answer is
The identity function, f(x) = x, is formed by the composition of a function and its inverse.

Answer:
46.2 square inches
Step-by-step explanation:
A parallelogram is a quadrilateral (4 sided closed figure) with 2 pair of parallel sides.
The diagram shown is a parallelogram.
Top and Bottom are parallel lines,
both sides are parallel lines (left and right).
The area for a parallelogram is given by:
Area = Base * Height
In the given figure, the base is clearly given as 4.2 inches
The height (perpendicular distance from base) is given as 11 inches.
<em><u /></em>
<em><u>So, basically we do not need the 11.7 inches length of side given.</u></em>
<em><u /></em>
Now, lets compute the area:
Area = base * height = 4.2 * 11 = 46.2 square inches
