Web6 de jan. de 2024 · Answer. Exercise 5.3.9. Solve the system by elimination. {3x + 2y = 2 6x + 5y = 8. Answer. Now we’ll do an example where we need to multiply both equations by constants in order to make the coefficients of one variable opposites. Exercise 5.3.10. Solve the system by elimination. {4x − 3y = 9 7x + 2y = − 6. Answer. There are many ways of writing linear equations, but they usually have constants (like "2" or "c") and must have simple variables(like "x" or "y"). But the variables (like "x" or "y") in Linear Equations do NOThave: 1. Exponents (like the 2 in x2) 2. Square roots, cube roots, etc Ver mais And there is also the General Formof the equation of a straight line: There are other, less common forms as well. Ver mais Sometimes a linear equation is written as a function, with f(x) instead of y: And functions are not always written using f(x): Ver mais Another special type of linear function is the Constant Function ... it is a horizontal line: f(x) = C No matter what value of "x", f(x) is always equal to some constant value. Ver mais There is a special linear function called the "Identity Function": f(x) = x And here is its graph: It makes a 45° (its slope is 1) It is called "Identity" … Ver mais
