Answer:
<em>A) (-5,7)</em>
Step-by-step explanation:
<u>Functions and Relations</u>
A set of values A can have a relation with another set B as long as at least one element of A has at least one image in B. Functions are special relations where each element of A (the domain of the function) has one and only one image on B (the range of the function).
By looking at the options, we can see that x=9, x=-8, and x=-1 already have defined values in Y, so if we define another value for any of them the relation will stop being a function. The only possible choice to preserve the function is the option
Write the vertex form of the equation and find the necessary coefficient to make it work.
.. y = a*(x +3)^2 -2
.. = ax^2 +6ax +9a -2
You require the y-intercept to be 7. So, for x=0, you have
.. 9a -2 = 7
.. 9a = 9
.. a = 1
The equation you seek is
.. y = x^2 +6x +7

Answer:
Option B that is (2,6) is correct
Explanation:
We have been given with system of equations
and 
Here, we will substitute the value of in
We will get 
Further simplification we will get to 
Hence, the value of 
And now, substituting the value in we will get 
.
Therefore, option B is correct.
Here, it is solved.
you only have to know:
The sum of the sides of a quadrilateral is equal to 360º.
