Answer:
Reflection over both y and x axes
Step-by-step explanation:
So we can see that all points have become their negative. If this only applied to x coordinates, this would have been a relfection over the y axis. If it only applied to x, it would be a reflection over the x. But since it applies to both, the answer is that it was a reflection over both axes.

Answer:
583$
Step-by-step explanation:
6% is equal to 0.06, so you multiply 550 by 0.06. which equals 33. Then, because it asks for how much Katie played, including the tax and TV, you add 33 to 550.
We know that if Two Complex Numbers (p + qi) and (a + bi) are said to be Equal then (p = a) and (q = b)
Given : (2x + 5) + (1 - y)i = -3 - 4i
⇒ 2x + 5 = -3
⇒ 2x = -3 - 5
⇒ 2x = -8
⇒ x = -4
Option 2 is the Answer
2x + 5 + i - yi = -3 - 4i
2x - yi = -8 - 5i
2x = -8 - 5i - yi
2x = -8 -i(5-y)
2(-4) = -8 -i(5-y)
0 = -i(5-y)
0 = 5 - y
-y = -5
y = 5
If x = -4, y is a real number.
