Answer: we multiply the second equation by -2. This property is the multiplication property of equality (1).
Then, we add the two equations generated. (2) addition property of inequality.
Next, we divide both sides of the equation by 13. That is division property of inequality.
Moreover, we substitute the value obtained for y in the first equation. This is substitution property of equality.
Then, we simplify
Next, we add +3 to both sides of the equation in order to have an equation with only one side having a variable. That is addition property of equality.
Lastly, we divide both sides of the equation by 4. This is division property of equality.
Step-by-step explanation:
the answer is 0=0 because there is infinite solutions
Answer: Graph D will be correct graph for the given function.
Explanation:
Given function 
Since it is a bi-quadratic equation thus it must have 4 roots and (0,1) is one of its point.
Moreover, the degree of the function is even thus the end behavior of the function is
, as
and
as 
In graph A, function has four root but it does not have the end behavior same as function f(x).( because in this graph
, as
and
, as
.) so, it can not be the graph of given function.
In graph B, neither it has four root nor it has the end behavior same as function f(x).(because in this graph
as
and
as
.) so, it can not be the graph of given function.
In graph C, neither it has four root nor it has the same end behavior as function f(x).(because in this graph
as
and
as
.) so, it also can not be the graph of given function.
In graph D it has four root as well as it has the same end behavior as the given function. Also it passes through the point (0,1).
Thus, graph D is the graph of given function.
