4 times 6 is equal to 24 so I did the same to 5 ( because 4/5) and then I got 30 so.
In six years he will be 24 and his brother will be 30 but in 4 years his brother Nick will be 28.

Identify examples and non-examples of the standard form of a linear function.
marin [14]

Answer:

  1. 5x - 3y = 9 (Example)
  2. y = 1/2x - 3 (Non-Example)
  3. 2x + 3y = 0 (Example)
  4. x + y = 1 (Example)
  5. x = 6y (Non-Example)
  6. y = x - 2 (Non-example)

Step-by-step explanation:

Standard form of the equation is given by:

Ax + By = C

Where

  • x and y are variables
  • A, B and C are constants which must be Integers. A should always be positive.

Considering the definition, we can identify the examples and non-examples of standard from of a linear equation.

<h3>5x - 3y = 9</h3>
  • In a form of Ax + By = C
  • A,B and C are constants
  • A=5 is positive

It is an EXAMPLE of standard form of linear function

<h3></h3><h3>y = 1/2x - 3</h3>
  • Not in the form of Ax + By =C

NON-EXAMPLE

<h3></h3><h3>2x + 3y = 0</h3>
  • In a form of Ax + By = C
  • A,B and C are constants
  • A=5 is positive

It is an EXAMPLE of standard form of linear function

<h3></h3><h3>x + y = 1</h3>
  • In a form of Ax + By = C
  • A,B and C are constants
  • A=5 is positive

It is an EXAMPLE of standard form of linear function

<h3></h3><h3>x = 6y</h3>
  • Not in the form of Ax + By =C

NON-EXAMPLE

<h3></h3><h3>y = x - 2</h3>
  • Not in the form of Ax + By =C

NON-EXAMPLE
