Is ( 0,0) a solution to this system? y< =x^2-4 y> 2x-1?

The point is not a solution of the system of inequalities

Step-by-step explanation:

we have

-----> inequality A

-----> inequality B

we know that

If a ordered pair is a solution of the system of inequalities

then

the ordered pair must be satisfy the inequalities of the system

Verify

For

substitute the value of x and the value of y in the inequalkity A and in the inequality B

Inequality A

-------> is not true

therefore

The point is not a solution of the system of inequalities

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
