What are two fractions that are equal to each other called?

An equation that sets two fractions equal to each other is called a proportion. A proportion is a name we give to a statement that two ratios are equal. When two ratios are equal, then the cross products of the ratios are equal.

What is the term for two fractions that are equal to each other quizlet?

proportion. two equivalent fractions set equal to each other.

What happens when two linear functions are added together?

Adding Linear Functions we saw when we added two linear functions f(x),g(x) we get a linear function whose slope is the slope is the sum of the slopes of f(x) and g(x) and y-intercepts are the sum of the y-intercepts of f(x) and g(x).

Is the sum of two linear expressions always linear?

Additions based on comments: The computerized system itself provided a statement, where you could change the answer from it being valid or not. It was of the form paraphrased “Your friend says the sum of two linear expressions is always a linear expression. 2 is a constant, and thus not a linear expression.

Can you multiply linear equation?

The key to using multiplying to solve linear systems is to find a number to multiply to one or both of the equations so that the x or y terms in one of the equations will have opposite coefficients from the x or y in the other equation. You would then add these two equations together. Add the two equations together.

How do we multiply functions?

Multiplication of Functions To multiply a function by another function, multiply their outputs. For example, if f (x) = 2x and g(x) = x + 1, then fg(3) = f (3)×g(3) = 6×4 = 24. fg(x) = 2x(x + 1) = 2×2 + x.

What are the steps in multiplication of function?

Step 1: Rewrite the function notation as the multiplication of two functions and then substitute the given expression in for each function. Step 2: Use the FOIL method or distribution, as appropriate, to multiply the two polynomials. Step 3: Combine like terms.

How do you add a function?

Operations on Functions: Adding and Subtracting Functions

  1. Addition. We can add two functions as: (f + g)(x) = f(x) + g(x) Example:
  2. Subtraction. We can subtract two functions as: (f – g)(x) = f(x) – g(x) Example:
  3. Multiplication. (f•g)(x) = f(x)•g(x) Example: f(x) = 3x – 5 and g(x) = x.
  4. Division. (f/g)(x) = f(x)/g(x) Example: f(x) = 3×2 + 4x – 3 and g(x) = x.
