Answer:
Reflection over y-axis
Step-by-step explanation:
We know that with a reflection of the x-axis, we flip the value of the y value
But since the y-values in Q3 and Q4 are both negative, we know that can't be the case
So it has to be a reflection over the y-axis where the x-values are flipped

2x^2-12x+18 this is the answer from my friend
Solution:
<u>Note that:</u>
- 3x + 50 = 6x - 10 (Vertically opposite angles)
Simplify the equation to find x.
<u>Add 10 both sides.</u>
- 3x + 50 = 6x - 10
- => 3x + 50 + 10 = 6x - 10 + 10
- => 3x + 60 = 6x
<u>Subtract 3x both sides.</u>
- 3x + 60 = 6x
- => 3x - 3x + 60 = 6x - 3x
- => 60 = 3x
<u>Divide 3 both sides.</u>
- 60 = 3x
- => 60/3 = 3x/3
- => x = 20
