Question about Texas Instruments TI-82 Calculator

Re: hi - Texas Instruments TI-82 Calculator Calculators

M=3 , b=-1

Re: hi

You should first put it in the form y=mx+b

m-slope

b-y-intercept

x + 2y=4

-x -x 1subtract x from both sides

2y=4-x

/2 /2 2 divide both sides by 2 (to get y alone)

y=2- x/2 now you can put that into your calc. (Y= button)it would like like this on your screen Y1=2-X/2 (X is found under mode)

next hit graph

2nd, TABLE will give you a list of x-values and y-values

hoped i didn't leave anything out and i hope this helped

To find the solution, first find the value of y for each equation.

Then substitue one equation into the other so that you only the x variable left.

Then just solve for x.

Once you have a value for x, then you can easily solve for y.

So for the first equation:

3y - 6x = -3

3y = 6x - 3

**y = 2x - 1**

Now for the second equation:

2y + 8x = 10

2y = -8x + 10

**y = -4x + 5**

Since both equations equal y, they also equal each other, therefore:

2x - 1 = -4x + 5

Now just solve for x:

2x + 4x = 5 + 1

6x = 6

**x=1**

Now substitute x=1 into either original equation:

y = 2x - 1

y = 2 (1) - 1

y = 2 - 1

**y = 1**

Therefore the solution is x=1 and y=1

Good luck, I hope that helps.

Just solve for 1 variable.

x+2y=4

2y=4-x

y=(4-x)/2

Now you can graph this and find all the values for x and y that give you the solution.

x+2y=4

2y=4-x

y=(4-x)/2

Now you can graph this and find all the values for x and y that give you the solution.

If you mean this to be a logic statement, it will always be false (0). You might be getting an error because you need parentheses around the whole thing.

If you mean the 2y=2 to be 2y 2 then y=2

If you mean the 2y=2 to be 2y-2 then y=4

You should give more info on your problem next time.

If those are the partial derivatives, then the stationary point should be (0,0). Because if you set the partial derivatives to zero and solve for x and y then the only solutions are x=0 and y=0.

One way is to use the Polynomial Root Finder and Simultaneous Equation Solver app.

Press the APPS key, then select PlySmlt2 and press ENTER. Press ENTER to get past the opening screen, then select "POLY ROOT FINDER" and press ENTER. Select the order of the polynomial and other settings as desired. Press F5 (the GRAPH key) to go to the next screen. Enter the polynomial coefficients, then press F5 to solve. The next screen will show you the roots (unless you selected real roots and the polynomial doesn't have any real roots).

If you don't have the app installed, you can download it from

to do that you replace x with y
ex: f(x)=2x+3 f(x) is your y so f(x)=y
you now have y=2x+3 switch x and y
x=2y+3 now solve for y
x-3=2y
(x-3)/2=y
y is now equal to the derivative of a function also shown as f^-1
(x-3)/2=f^-1(x)
all ^ mean to that power

Having gone over a month with no response, I assume it was just a contrast problem, solved by my suggestion.

The easiest solution would be to move the variable to only one side. This is not that difficult. For example your given equation is 8(3x-5)-4=4x-10; subtracting both sides of this equation by 4x would give 8(3x-5)-4-4x=10.
