Which of these is a reason to substitute the values back into the equations when solving a system by graphing?
you cannot determine the exact value of the point
How do you solve equations using square root?
The answer will depend on the exact nature of the equation.
Exact solution for Tan theta equals negative square root of 3?
Negative 1.047197551 etc, etc.
What could be the equation of a parabola with its vertex at -3 2?
-1
What is the equation of a Parabola with a vertex of 5 -4?
9
How can graphs be used to estimate the solution for a system of linear equations?
Graphs can be used in the following way to estimate the solution of a system of liner equations. After you graph however many equations you have, the point of intersection will be your solution. However, reading the exact solution on a graph may be tricky, so that's why other methods (substitution and elimination) are preferred.
What is the exact solution to cosx equals x?
There is no "exact" solution. This type of equation falls into the category of transcendental equations, which generally don't have exact solution except in special cases. The approximate solution, however, is roughly 0.739085
How many solutions does the nonlinear system of equations graphed when the graph open up and down?
A system of equations means that there are more than one equations. The answer depends on the exact function(s).
What is the limitation of Schrodinger equations?
The biggest limitation by far is that an exact solution is possible for only a small number of initial conditions. For example, one can figure out the solution for permitted states of one electron around a nucleus. However, there is no exact solution for even two electrons around a nucleus.

Why is trial and error so useful in math?
There are many equations for which there is no method for obtaining an exact solution. In such circumstances, an efficient trial and error method may be the only way.
What is the difference between the exact solution and a approximate solution?
An exact solution is the accurate solution, whilst an approximate solution is only near enough
What are the pros and cons of using the substitution or elimination method in equations?
A pro for solving equations through graphing can allow one to visualize problems which can allow one to make better sense to the problem. However, fractions, and decimals can be very difficult to plot accurately. Furthermore, solutions could fall outside of the boundaries of a graph making them impossible to see with a graph. A pro for solving equations through either the methods of substitution and elimination allow one to achieve an exact answer regardless of fraction, decimal, or integer. However, by using these methods one will have a more difficult time with visualization without the use of a graph.
How do you solve equations using square root?
The answer will depend on the exact nature of the equation.
What is the answer to 13x-2y equals 70 and 2x-2y equals 4 using the method of substitution?
i am guessing here that this is what you mean as it involves substitution: 2x-2y = 4 therefore -2y = 4 - 2x Sub the above line into the first equation gives: 13x - 2x +4 = 70 11x = 66 x=6 then sub in x 13(6) - 2y = 70 78 - 2y = 70 y=4 Yep, this is the exact same as simultaneous equations
What is a word for the substitution of space for time?
There is not an exact "word", but what I can say is that it deals with researchers studying succession by comparing sites of various ages
Can you substitute orange exact for orange bitter?
my recipe calls for an orange bitter and I am asking if I could use orange extract for substitution.
