When the head rotates or tilts, the otoliths in the vestibule sacs shifts, causing the fluid in the semicircular canals to move, bending hair cells, which turn in activate neural signals and notify them about the head's position and movement. The vestibule nerve connects with the cochlear nerve to form the auditory nerve, which relays information to the brain about balance.
The system would equal (1.65,-0.25)
You can use substitution for this. But first we need to put one of the equations into the value of y or x. We can use 5x+y=8 and solve for the value of y. Subtract 5x on both sides and you’ll get the value of y which will look like y=-5x+8.
Next substitute in y for 5y in 5x+5y=7 so that you get 5x+5(-5x+8)=7. Next distribute and you’ll get 5x-25x+40=7, add like terms and you’ll get -20x+40=7. Next you want to subtract by 40 on both sides and you’ll get -20x=-33. Isolate x by dividing by -20 on both sides and you’ll get x=33/20 or 1.65.
Next that you have the x value solve for y by plugging in 1.65 for x in 5x+y=8 and you’ll get 5(1.65)+y=8, distribute and subtract 8.25 on both sides and it will leave you with y=-0.25.
Unexpected means it was something you did not "expect" to happen such as a car crashing into you which means this is wrong.
Unfair is any injury.
Unnecessary means it was never needed and could have been prevented/not done therefore unnecessary is the best term.
