Question

A gardener will use up to 250 square feet for planting flowers and vegetables. She wants the area used for vegetables to be at least twice the area used for flowers. Let x denote the area (in square feet) used for flowers. Let y denote the area (in square feet) used for vegetables. Shade the region corresponding to all values of x and y that satisfy these requirements.

Answer 1

To plot the region that satisfies the requirements, we can start by setting up the inequalities:

y ≥ 2x (the area used for vegetables is at least twice the area used for flowers)

x + y ≤ 250 (the total area used for planting is at most 250 square feet)

We can plot these inequalities on a coordinate plane to find the shaded region:

First, plot the line y = 2x (Load failedboundary line for the first inequality). This line passes through the origin and has a slope of 2, so we can plot additional points using this information. For example, when x = 50, y = 100 (since 100 is twice 50).

So, the shaded region on the coordinate plane corresponds to all values of x and y that satisfy the given requirements.

Answer 2

Explanation:

We can start by setting up the following system of inequalities to represent the requirements given in the problem:

x + y ≤ 250 (the total area used should not exceed 250 square feet)

y ≥ 2x (the area used for vegetables should be at least twice the area used for flowers)

To graph these inequalities, we can first graph the boundary lines for each inequality:

x + y = 250 (the boundary line for the first inequality, with points (250, 0) and (0, 250))

y = 2x (the boundary line for the second inequality, with points (0, 0) and (125, 250))

Then, we can shade the region that satisfies both inequalities, which is the region below the line x + y = 250 and to the right of the line y = 2x:

The shaded region represents all values of x and y that satisfy the requirements given in the problem, where x is the area used for flowers and y is the area used for vegetables. The x and y values in this region can vary, as long as the total area used is less than or equal to 250 square feet and the area used for vegetables is at least twice the area used for flowers.
