The function y = 6 + 2x can be used to find the perimeter y of a rectangle with dimensions x inches and 3 inches.

The function y = 3x can be used to find the area y of the rectangle with dimensions x inches by 3 inches. i also have to do an input output table for both equations there labeled 1 - 7

Explanation:

The function y = 3x represents the area y of a rectangle with dimensions x inches by 3 inches. To find the area of the rectangle, we multiply the length (x) by the width (3).

To create an input-output table for this function, we can choose values for x and calculate the corresponding values for y.

Here is the input-output table for the function y = 3x:

| x (inches) | y (area) |

|------------|----------|

| 1 | 3 |

| 2 | 6 |

| 3 | 9 |

| 4 | 12 |

| 5 | 15 |

| 6 | 18 |

| 7 | 21 |

In this table, we start with x = 1 and calculate y = 3x. For example, when x = 1, y = 3(1) = 3. When x = 2, y = 3(2) = 6, and so on.

By substituting different values of x into the equation y = 3x, we can determine the corresponding areas (y) of the rectangles with dimensions x inches by 3 inches.
