Given -3x + 2y = 1 and x = 5, solve for y. a.-7 b.7 c.-8 d.8

Step-by-step explanation:

1. You already know the value of the variable , which is:

2. Therefore, you need to substiute the value   into the equation and then you must solve for , as following:

3. The result is:

chicken chicken chicken

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
