10
Step-by-step explanation:
5x+2=9x-38
-4x=-40
x=10
Answer:
x - y = 0
Step-by-step explanation:
The given line is y = x.
We could re-write this as x - y = 0, which is in general form.
Just take a calculator and divide 4 by 10 exactly how you see it. Or just divide it like you normally would any number on paper. 0.4 is your answer.
Answer:
symmetry about the y-axis is shown
Step-by-step explanation:
Points on the right of the line of symmetry (x=0, the y-axis) are the same distance from that line as the corresponding points on the left. (That is what makes it a line of symmetry.)
There is no point of rotation that will map one figure to the other after rotation, hence no point or rotational symmetry.
