What is the solution to the inequality? −4x−8> −20 a. x> 3 b. x< −3 c. x< 3 d. x> −3

x > 3 ( A )

Step-by-step explanation:

from the inequality equation we have

-4x - 8> -20 in order to solve the inequality we move the variable to one side

equation 1 becomes

-4x >  -20 + 8

therefore

-4x > -12 hence dividing both sides of the inequality by -4 will be to get the value of x

equation 3 becomes

-4x/-4 > -12/-4

x > 3 canceling out the negative signs on both sides the answer becomes

x > 3

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
