Step-by-step explanation:
i wont be symmetric at 90º or 270º or 120º or 240º. and it has rotational symmetry
Answer:
that means the system has no solutions
12/15,7/25,3/7,3/5 should be correct because this is what my teacher taught me in fourth grade.
Lets say you have an addition problem
3 + 7 = ?
To figure that you can just add in your head since its easy.
3 + 7 = 10
You can work backwords to check to see if your awnser is right.
When you work backwards you do the opposite of what you are doing, so if your adding the opposite would be subtracting, and if your multiplying than the opposite would be dividing.
So you could work it out like this:
(Regular⬇️)
3 + 7 = 10
(Backwards⬇️)
10 - 7 = 3
And if you get the same numbers that were in the original awnser than you are correct! Hope this helps!!!!
The answer would be 7y+35
