Answer:
second picture
Step-by-step explanation:
The rule to rotate a point counterclockwise about the origin is:
Or in words, we switch the coordinates of the point and change the sign of the y-coordinate.
We know from the first picture that the coordinates of our quadrilateral ABCD are A = (-1, 0), B = (0, -1), C = (-2, -3), and D = (-3 , -2), so let's apply the rotation rule to each one of those points:
Now we know that the coordinates of the quadrilateral after a rotation of 90° are A' = (0, 1), B' = (1, 0), C' = (3, -2), and D' = (2, -3), which corresponds to the second picture
We are given expression:
.
Tyna simplified the given expression to
.
Explanation: In order to simplify
, Tyna need to simplify rational expression
.
On dividing top and bottom by 3, we get
.
Which Tyna got correct.
Now she need to simplify
.
<em>On applying quotient rule of exponents, we need to subtract the exponents of x's.</em>
So, it would be
.
<h3>So, the final answer should be

.</h3><h3>Therefore, Tyan forgot to add exponent to x.</h3><h3>The exponent of x should be 5.</h3>
Im not really sure
But hope I still get it

Answer:
B. 10
Step-by-step explanation:
If this is a list of statements in a programming language that is processed sequentially, y is assigned the value 9+1 = 10. There is no further assignment to y, even after the value of x is changed. So, the final value of y is 10.
__
<em>Additional comment</em>
Some programming languages do their processing in parallel, so that the definition of y would be updated when the value of x gets updated. In that case, the value of y would be changed to 5+1 = 6. Since this is not a choice, the problem is apparently supposed to be interpreted as above.
