3•f(-4)-3•g(-2) = ???

evaluate function expression

3•f(-4)-3•g(-2)

= -12f+6g

factorized form by taking common in both

= -6(2f-g) or 6(-2f+g)

( first one is minus 12f because plus into minus = minus)

(second one is plus 6g becuase minus into minus= plus)

step-by-step explanation:

15   3/4 / 3 = 5   1/4

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
