Linear relationship Explain how you can use a linear function to solve this problem. Then, solve the problem.

If you keep not spelling out the TEXT of the problem, there is zero chance that you will get an answer, regardless of the number of posts you write. No one is a mind reader.

Which of the following equations? What following equations?

This is not the kind of material for this site, we are a self help repair and use site for manufactured products.

All graphs, except the linear function y=ax+b, are non-linear. To graph a function, just enter the GRAPH utility, type in the functions Y1=, Y2=, ... and press the Draw tab.
If you have a specific question, ask it.

Turn Calculator ON.
In scratchpad, add a Graph.









After you press enter to graph the function you will not see anything because the y-intercept is at ordinate 254.47. To see anything you need to zoom out.



You will be prompted for the Center of new graph. Move cursor along the y-axis, upward. After a while you will see the graph.




You can also, and it is quicker, to set the graph window





Set the values as on the screen capture





Here is what you see


Enjoy.

You can solve equations two ways: The EQN computational mode or the SOLVE application.
IN the EQN mode you can solve linear equations in one, two and three unknowns; the quadratic equation; and the cubic equation.
Enter the EQN mode by following the instructions on the following screen capture. Press 5:EQN

You have three types of equations.

Once you select the type of equations, a template is displayed where you enter the relevant coefficients.


Under each label (a, b, etc. ) enter a coefficient and press ENTER to move to the next. With a cubic equation, or a linear equation in 3 unknowns, you have to use the Right arrow to display the cells where you enter the value of d.
After you input all necessary coefficients press the = sign to get the solution.

To use the SOLVE feature, see the screen capture that follows. It comes from the Casio manual.






Good luck

Set Computational mode to EQN by pressing [MODE][5:EQN]

Select the type of equations you want to solve

Select the relevant otion and get ready to type in the coefficients (the a's, the b's, the c's etc`.)

For more general non-linear equations, use the SOLVE feature.

4x+7=11 Solve for "x".
subtract 7 from each side of the equation
4x +7(-7)=11(-7) = 4x=4
divide both sides of the equation by 4
4x/4=4/4
therefore
x=1
Correct?

2x-3 = 3-3(x + 3)
