<span>The answer: b. translated according to the rule (x, y) → (x + 8, y + 2) and reflected across the x-axis
If you make the drawing of the situation you realize the you need a reflection through the x-axis, but first you need to translate the polygon several units to the left and upward.
You can see that all the x-coordinates have increased 8 units, so the solution has to include x + 8.
Also, you see that you have to move the polygon 2 units upward before doing the reflection so the solution has to include y + 2.
So, the answer is (x,y) ---> (x + 8, y + 2) and then reflection across the x-axis.

Answer:
r=3
Step-by-step explanation:
- The equation of a circumference is
. - Then , in this case
, and then to know the value of r we just simply have to calculate the square root of 9, which is 3.
30: r = -32
38: n < -24
54: ?
Answer: The value of 'h' is 3.
Step-by-step explanation: Given that the vertex form of a function is given by
We are to find the value of 'h' when the following function is converted to the vertex form.
From equation (ii), we have
Comparing it with the vertex form (i), we get
Thus, the value of 'h' is 3.
