( y= -4x - 3
( y = -2x + 1

Find the solution to the system of equations.

x=-2 y=5

Step-by-step explanation:

1. plug in for y

-2x+1=-4x-3 (then just solve)

2x+1=-3

2x=-4

x=-2

then plug in the other

y=-4(-2)-3

y=8-3

y=5

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
