What is 8y + 10 − 4 − 5y equal to?

3y+6

Step-by-step explanation:

Simplify step-by-step.

8y+10−4−5y

=8y+10+−4+−5y

Combine like terms:

=8y+10+−4+−5y

=(8y+−5y)+(10+−4)

=3y+6

-2

Step-by-step explanation:

8y+10-4+5y

10+ -4 + 8y + -5y =0

10+ -4=0

6+8y + -5=0

8y + -5y= 3y

6+3y=0

6+ 3y =0

then add -6 at the end of the equation

6+-6+3y=0+-6

continue term

6+-3+3y=0+-6

3y = 0 + -6

combine term

0+3y=0+ -6

3y = 0 +-6

divide each side by 3

and you get -2

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
