Multiply out the brackets first.
So 2(-4y-9)-5y becomes -8y-18-5y [2 times -4y and 2 times -9]
Then simplify -8y-5y-18 to the answer ......-13y-18 or -(13y+18)
The rule of reflection is ry-axis (x , y) → (-x , y)
Answer:
set both of them equal to each other:
8x - 8° = 5x + 25°
subtract 5x by both sides of the equations and it becomes:
3x-8° = 25°
now add 8° both sides:
3x = 33°
divide three by both sides:
x = 11°
now thats done to find B:
plug your x value in the B equation:
5x + 25°
5(11) +25°
55 +25°
not sure if you can add here sorry :(. I hope this helped so far :)
