First of all you equation is not one : it has nothing on the right side of the = sign. But to answer the general question let us write the equation as **50+25x-5y=0**

**X-intercept (also know as roots) There may be several**

Definition: X-intercepts are those values of the independent variable x**for which y=0**. For a straight line there con be at most 1 x-intercept.

To find the intercept, set y=0 in the equation of the line and solve for x

50+25x-5(0)=0 or 50+25x=0. The solution is** x=-(50/25)=-2**

**Y-intercept (also know as the initial value.** There can only be 1 y-intercept, otherwise the expression does not represent a function.

Definition: It is the value of the dependent variable y when x=0 (where the function crosses the y-axis

To find it, set the x-value to 0 in the equation of the line.

**50+25x-5y=0**

50+25(0)-5y=0, or 50-5y=0. The solution is**y=50/5=10**

The straight line cuts the x-axis at the point (-2, 0) and the y-axis at the point (0,10)

- You have several memory locations you can use to store values in them. The memory locations are A,B,C,D, M, X, and Y. You use [SHIFT][RCL] and one of the variable names above. Example store 78 in C location: 78 [SHIFT] [RCL] [HYP]. To recall that value press [RCL] [HYP]

- If you want to use the EQN (equation solving mode, press [MODE][5:EQN] then select the equation type . For example [3:aX^2+bX+c=0] will display a template wher you input the three coefficients.

- You can also enter any type of equation and solve it with the SOLVE command. In that case you use the keyboard to enter the expression (see above how to enter variable name X). To type in the equal sign (=) use [ALPHA][ CALC]. Once the whole equation is typed in, press [SHIFT[ [SOLVE], and the calculator will prompt SOLVE for X? Confirm and press the main = sign. Press = again to get a second, a third root (if any)

Here is some help

180deg is equivalent to Pi radians

Take some angle. Its measure in degrees is say x_deg, Its measure expressed in radians is x_rad.

The fraction of 180 deg that the angle represents is equal to the fraction of PI that this angle represents.

Conclusion: the ratio x_deg/ 180 deg must be equal to the ratio of x_rad/PI

x_deg/180 deg=x_rad/PI

Isolate X-rad in the above equation. Some will tell you to cross multiply.

x_rad=(Pi/180)*x_deg

Application: x_deg=-525 in radians?

x_rad= (PI/180)*(-525)=-(525/180)*PI

Keep the value (525/180) as a fraction reduced to its simplest form. The result is 35/12

You cannot solve the quadratic equation with this calculator. It does not have a solve program.

However if you wnat to create a table of values for a function (any type of function that uses the basic scientific function keys ) you use the TABLE Computational Mode.

You press MODE

You select TABLE

You enter a mathematical expression 3X^2-.33X+ 15

You generate the table of values.

Well, the short story is that this calculator cannot do symbolic algebra: it does not have a CAS (Computer Algebra System). However you can enter symbolic expressions using the variables A,B,C,E, X and Y. Use the sequence [ALPHA] [A] to enter the letter A, etc. To type in the symbolic = sign, use the [ALPHA] followed by the key at the top left corner of the keypad that has an = next to it.

When you enter an equation (two expressions linked by an =), press [ALPHA][SOLVE] to solve the equation for tha unknown X. You will be prompted to enter the values of all other letter symbols : A,B,C, D, Y, etc. When all symbols (except X) have been given a value the calculator will find the value of X that satifsfies the equation.

n mathematics, an **expression** is a finite combination of symbols that are well-formed according to the rules applicable in the context at hand. Symbols can designate values (constants), variables, operations, relations, or can constitute punctuation or other syntactic entities.

Any "expression" that represents a numeric value. Example: 2+2=4 or x+7=10. Actually the examples above are equations, not expressions. Expressions do not have = signs. 7a and 4x are examples.

it is a mathematical statement e.g 7=**6+1** THE WHOLE THING IS AN EQUATION but the 6+1 is a expression.You can only have expression is there is an = sign

Yes the 6 + 1 part is an expression. Once you have an = sign or any of the other inequality symbols (,...) it is no longer an expression but a full math sentence

This expression 5x^2+15x+3 is not an equation, therefore it can have any value depending on the value of x. You have to make it an equation before looking for the particular value of x that satisfy your equation **5x^2+15x+3 =0**

This calculator cannot solve equations because it does not have an equation solver.

You can use symbols (X,Y,A,B,C,D, and M, =) to create expressions to use
in the SOLV program or to generate a table of values.

To type them you use [ALPHA] followed by the symbol you want. The symbols on the body of the calculator are of the same color as the ALPHA key. The [=] in expressions is different from the general = sign at the bottom of the keypad.

There are also some typical equations already in the calculator: simultaneous linear equation in 2 or 3 unknowns, and polynomial equations of 2nd and 3rd degree. They are accessed under the EQUATion Mode.

Hi,

First let us repair the terminology.

Hope it helps.

Thank you for using FixYa and for rating this solution.

First let us repair the terminology.

- You can evaluate any expression (find the value of any expression for a particular value of its variable).Store a value in the variable, say X. Key in the expression and press [EXE].
- You can consider your expression(should not contain a relational operator such as =, greater than, less than, greater than or equal to, less than or equal to) to be a function Y1(x) = expression and graph it, or generate a table for it. You will have several values of the function calculated at various points.
- You can set your expression equal to 0 and find the particular value(s) of the variable (the unknown) that make the equality TRUE. That is called solving an equation.

Hope it helps.

Thank you for using FixYa and for rating this solution.
