Answer:

In addition, from the response shown, using a graphical calculator brings the following benefits:

1) You can write the system of linear equations as big as you want. This is: systems 3 * 3, 4 * 4, 5 * 5.

2) The response to systems of equations greater than 2 * 2 can be complicated when you graph the solution, therefore, the graphing calculator can be much more efficient in these cases.

3) You can write the linear equations in any way. Resolving by hand you should probably rewrite the system of equations to find the solution.

Answer:

Step-by-step explanation:

It is much simpler to graph and find the intersection points between the equations, which would be the solutions to the system, than graphing it by hand which would lead to some errors.

To isolate c means to separate it completely on one side of the equals sign.

To isolate variables, you apply opposite operations.

In E = mc², m and c are being multiplied together. To separate them, you divide by the variable you want to get rid of. However, you must do this to both sides of the equation always. Whatever you do to one side of the equation you must do to the other side as well. This is so the equation remains true.

Since we want to isolate c, we'll start by dividing both sides by m.

E = mc²

E/m = mc²/m

E/m = c² -- The m's cancel as 1

Now we have c squared. The opposite of squaring something is taking its square root. Take the square root of each side.

E/m = c²

√(E/m) = √(c²)

√(E/m) = c -- Opposite operations cancel each other out

And you've isolated c!

Answer:

c = √(E/m)
