just multiply 40 times 3 and you will get 120
I believe the answer is y ≤ -3x + 5.
I have not learned inequalities yet so if I am wrong, then :/
According to m.a.t.h.w.a.y:
1) 1.72
2)-0.4
3) if you mean 10/3-76= -72.7
if you mean 10/3-7/6= 2.2
The positive x axis in polar coordinates is called a pole
