Answer:
90.
Step-by-step explanation:
We have two lines of code:
y ← x + x + x + x + x
z ← y + y + y
and, x=6 before the execution. Then, when the program starts to run we obtain:
y ← 6 + 6 + 6 + 6 + 6
y ← 30
z ← 30+30+30
z ← 90.
Then, the value of z after excecution is 90.
180 degree rotation negates both coordinates, and takes a point from quadrant 2 to quadrant 4.
Answer: 4
We can also rotate 180 degrees clockwise, or 540 degrees counterclockwise and end up in the same place.
Combining transformations, we can reflect in the x axis and then in the y axis, also negating both coordinates so equivalent to 180 degree rotation.

Ok
First factor out the first 2 terms as follows:-
y = 1/2(x^2 - 8x) + 21
Now complete the square on x^2 - 8x:-
y = 1/2[ (x - 4)^2 - 16] + 21
y = 1/2(x - 4)^2 - 8 + 21
y = 1/2(x - 4)^2 + 13 Answer
