Solve the equation -2(y - 1) = 9

-7/2

Step-by-step explanation:

−2(y−1)=9

(−2)(y)+(−2)(−1)=9       (Distribute here)

−2y+2=9  

−2y+2−2=9−2           (Substract 2 from both sides)

−2y=7                         (Divide both sides by -2)

y= -7/2

have a spoopy halloween lol :'D

-3.5

Step-by-step explanation:

-2(y-1)=9

-2y+2=9

9-2=7

7/-2y

-3.5

1 is c

2 is a

3 is a

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
