ANSWER :
a. {2, 6, 9}
b. {6}
EXPLANATION :
From the problem, we have the sets :
![\begin{gathered} U=\lbrace2,3,4,6,9\rbrace \\ A=\lbrace2,3,4\rbrace \\ B=\lbrace3,4,6\rbrace \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20U%3D%5Clbrace2%2C3%2C4%2C6%2C9%5Crbrace%20%5C%5C%20A%3D%5Clbrace2%2C3%2C4%5Crbrace%20%5C%5C%20B%3D%5Clbrace3%2C4%2C6%5Crbrace%20%5Cend%7Bgathered%7D)
A' denotes the elements that are NOT present in A but present in U.
B' denotes the elements that are NOT present in B but present in U.
That will be :
![\begin{gathered} A^{\prime}=\lbrace6,9\rbrace \\ B^{\prime}=\lbrace2,9\rbrace \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20A%5E%7B%5Cprime%7D%3D%5Clbrace6%2C9%5Crbrace%20%5C%5C%20B%5E%7B%5Cprime%7D%3D%5Clbrace2%2C9%5Crbrace%20%5Cend%7Bgathered%7D)
a. A' ∪ B'
The symbol ∪ denotes the union of two sets.
That will be :
![A^{\prime}\cup B^{\prime}=\lbrace2,6,9\rbrace](https://tex.z-dn.net/?f=A%5E%7B%5Cprime%7D%5Ccup%20B%5E%7B%5Cprime%7D%3D%5Clbrace2%2C6%2C9%5Crbrace)
b. A' ∩ B
The symbol ∩ denotes the intersection or common elements of the two sets
That will be :
Answer:
<h2>
x= −5−11√13/2, −5+11√13/2</h2>
Solve the equation for x by finding a, b, and c of the quadratic then applying the quadratic formula.
Exact Form:
x= −5−11√13/2, −5+11√13/2
Decimal Form:
x=17.33053201…,
−22.33053201…
Step-by-step explanation:
x(x+5)=387
Simplify
x(x+5).
x^2+5x=387
Subtract 387 from both sides of the equation.
x^2+5x−387=0
Use the quadratic formula to find the solutions.
−b±√b^2−4(ac)/2a
Substitute the values a=1, b=5, and c= −387 into the quadratic formula and solve for x.−5±√5^2−4⋅(1⋅−387)/2⋅1
Simplify.
x=−5±11√13/2
The final answer is the combination of both solutions.
x=−5−11√13/2, −5+11√13/2
The result can be shown in multiple forms.
Exact Form:
x=−5−11√13/2,−5+11√13/2
Decimal Form:
x=17.33053201…,
−22.33053201…

Answer:
B.
Since it is mirrored, it can also be said that it is a reflection instead of simply a rotation. It is mirrored from left to right, therefore it is reflected about the y-axis. Lastly, it is true that it would have a translation left by 2 units, as you can see it needs to "travel 2 units" to read A'B'C'D'.
