Alex owes his father $100. his father pays him $12.50 an hour to work at their family store. the function d=100-12.5h represents the amount of debt d alex has. how many hours will it take him to pay off his debt?

8 Hours.

If you want his debt to be 0, as in he has nothing left to owe, we will set d (his debt) to 0

0 = 100 - 12.5h

Subtract 100 to move it to the other side

-100 = -12.5h

Divide each side by -12.5

8 = h

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
