Heyy! i’ll give brainliest please help.

seismic wave -

an elastic wave in the earth produced by an earthquake or other means.

explanation:

reflecting point a across the origin negates both of its coordinates.

b = (5, -4)

for e2020. the answer would be some directions from the mountain range so we can find mt. whitney. to locate which direction is north, you should use a   compass. this would not only find mt. whitney, but also becuase of this long paragraph you would get points because it's not like anyone actually reads your work becuase once they read the first sentence it sounds dumb enough to not read becuase i'm not good at answering this but the answer is compass for your benefit.

for e2020 ; -;
