Answer:
x axis
Step-by-step explanation:
We know the x value stays the same. If you were to graph the line y=3 and y=-3, you would see that it is a reflection over the x axis.
An x or a cross_____________
4+3+1+1+1+1+1 =12
4x3x1x1x1x1x1=12
Cos x = 15÷17
because cos is adjacent side over hypotenuse.
