Answer:
DY
Step-by-step explanation:
TO ENCRYPT TO USING CAESAR ALPHABETIC SHIFT CIPHER OF 10. THIS MEANS WE'RE EXPECTED TO LOOP EVERY ALPHABET BY 10, SKIPPING EVERYONE TILL WE GET TO THE TENTH.
TO ENCRYPT T, WE HAVE
T = U - V - W - X - Y - Z - A - B - C - D
THEREFORE, T WILL BE ENCRYPTED AS D
TO ENCRYPT O, WE HAVE
O = P - Q - R - S - T - U - V - W - X - Y
HENCE, O WILL BE ENCRYPTED AS Y.
THIS MEANS THAT OUR QUESTION, TO, WILL BE ENCRYPTED AS DY
The answer is A
(0,0) (1,2) (3,-3)
Answer:
C
Step-by-step explanation:
When completing the square, we essentially want to create a perfect square trinomial by adding a constant.
If we have the following expression:

And we want to complete the square, we will need to divide the b-coefficient by half and then square it.
Thus, the added term should be:

In the given equation, we have:

The b term here is 8. Therefore:

The value we would add would be 16.
The answer is C.
Further notes:
To complete the square, add 16 like mentioned earlier. However, we also need to subtract 16 to balance things out:

The expression inside the parentheses is now a perfect square trinomial. Factor it:

And we are done!
3y + 12 = 6x
3y = 6x - 12
y = 2x - 4
2y = 4x + (-8)
y = 2x + (-4)....the same as y = 2x - 4
b would have to be a -8
