Answer:
Step-by-step explanation:
first subtract 125-180=X you will get X=55 so then add X+X+y=180 which x+x+y= is actually 55+55+y=180 but don't add the y just yet add 55+55 then you will get 110+y=180 so then flip it backwards and do y=180-110 and your anwser is y=70
Answer:
The first one is x axis
the second one is the axis
third one doesn't seem to be a reflection
Answer:
Presumably the first graph solely based on its shape.
Answer:
-5x - 8y = -5
Step-by-step explanation:
Whenever we two equations, we are essentially just adding the left sides up and then the right sides up. Here, let's write these into one whole big equation:
(4x - 4y) + (-9x - 4y) = -2 + (-3)
Taking the parentheses out, we have:
4x - 4y - 9x - 4y = -2 - 3
Combine like terms:
4x - 9x - 4y - 4y = -5
-5x - 8y = -5
Hope this helps!
All the points listed below are parallel to each other, meaning that both triangles are equivalent to each other.
