An algebra teacher is ordering new text books for the class. The shipping cost y
y (dollars) depends on the number
x
x of books that are ordered, as shown in the table. Write a linear model in slope-intercept form for this data where
y
y represents the shipping cost and
x
x represents the number of books.

a - base

b - exponent

so,

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
