Solve. 3x + 1 < 2x - 2 < 5x +7 a) x < -3 and x > -3 b) -3 < x < 3 c) x < -3 d) no solution

no solution

Step-by-step explanation:

(you do the exact same you'd do in an equation problem. Get x by itself)

3x+1<2x-2<5x+7

1 < -x-2 < 5x+7

3< -x < 5x+9

3 < -6x < 9

-(1/2) > x > -(3/2)

x can't be bigger than -3 halves and be smaller than -1 half, so the answer is no solution

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
