Question about Casio FX-300MS Calculator

See this solution http://www.fixya.com/support/t663157-calculate_equation,

also in the case of your example:

4y=2x4 (4 times y = 2 times x times 4, moving the 4 over makes it divide by 4)

y=__2x4__ (the 4's cancel out, 4 divided by 4 = 1, 1 times anything is the same)

4

so y=2x (if we move x over it becomes divide by)

so __y__=2 (y diveided by x = 2 is as far as you can go)

x

I think the problem with this equation comes when x = 0. At this point, it is undefined. Thus, it is a horizontal line y=-2, except when x=0. This is normally signified by putting an open circle when x=0.

I hope I answered you question. If not, repost.

Good luck,

Paul

First, I graphed the lines and the point using Desmos.com.

I noticed that the two lines are perpendicular to each other and the point (1,-1) appears to be on the right side of the circle, on a line parallel to 3x -4y-10=0. The equation of this line is y= 3/4x - 1.75. The y-intercept is -1.75. Now we have two points on the opposite sides of the circle, (1, -1) and (0,-1.75). The midpoint formula will give you the centre of the circle and the distance formula will provide the radius.

Let me know if you have any questions.

Good luck.

Easy to verify. Put 4 instead of x in the equation. You get 2*4+4?=0. Obviously 2*4+4=3*4=12, and 12 is not equal to zero. The value x=4 is not a solution of the equation.

**2x+4=0, gives 2x=-4 and x=-4/2=-2**

inside the menu , there is an option EQN . take it and then there will be a list of type of eqns according to the order of the function . The eg u said above wil be the 1st type. enter that mode
then it will ask for values 1 by 1 .

Graph 2X PLUS 1 for X in open interval ]-1,0[

It should be entered as follows

(2X plus 1) (X larger than negative 1) (X less than zero)

In [Y=] editor and on line Y1= type your right hand side between parentheses (2X Plus 1). I use the Plus instead of the usual sign because the parser of the web site removes the sign.

[( ]2 [X,T,theta,n] [Plus] 1 [)] [(] [X,T,theta,n] [2nd][MATH] [3: larger than] [(-)] 1 [)] [(] [X,T,Theta,n] [2nd][MATH][5: less than] 0 [)]

Go to your matrix button and enter a "3x4" matrix.

Then enter it as follows:

-3 4 5 7

4 3 2 9

-5 5 3 -10

Then exit out and go to "2nd->matrix->math->rref(". Then press enter.

Your screen should look like this:

rref(

Then go to matrix and select your 3x4 matrix, press enter and close it with a parathesis. Your screen should look like this:

rref([A])

Press enter and the screen should say this:

1 0 0 2

0 1 0 -3

0 0 1 5

So,

x=3

y=-3

z=5

Hope this cleared up the confusion!

The STO> button just above the on/off button is your memory store initializer.

example: 2x + 53 STO> y

stores "2x + 53" in a variable named "y".

To recall, just hit y and enter. In fact, if you type an equation like 3y^2 - 4y it will insert the data in for every "y" and give you:

(2x + 53)(6x + 155) as an answer.

To clear the memory:

DelVar y or F6 (2nd+F1) and clear all w/ single character names.

To recall a prevous answer, 2nd+(-) or type ans(1) for the last answer. You can also type ans(2) for the 2nd to last answer & so on.
