3x + 1y = ¹/₃   ⇒ 9x + 3y = 1
2x -  3y = 2²/₃ ⇒ 2x -  3y = 2²/₃
                                 11x = 3²/₃
                                  11     11
                                     x = ¹/₃
                             3x + y = ¹/₃
                         3(¹/₃) + y = ¹/₃
                               1 + y = ¹/₃
                             - 1        - 1
                                     y = ⁻²/₃
                              (x, y) = (¹/₃, ⁻²/₃)

Explain how to modify the graphs of f(x) and g(x) to graph the solution set to the following system of inequalities. How can the
Norma-Jean [14]

The graphs of f(x) and g(x) are transformed function from the function y = x^2

The set of inequalities do not have a solution

<h3>How to modify the graphs</h3>

From the graph, we have:

f(x) = x^2 -3 and g(x) = -x^2 +2

To derive y < x^2 - 3, we simply change the equality sign in the function f(x) to less than.

To derive y > x^2 + 2, we perform the following transformation on the function g(x)

  • Shift the function g(x) down by 2 units
  • Reflect across the x-axis
  • Shift the function g(x) down by 3 units
  • Change the equality sign in the function g(x) to greater than

<h3>How to identify the solution set</h3>

The inequalities of the graphs become

y < x^2 - 3 and y > x^2 + 2

From the graph of the above inequalities (see attachment), we can see that the curves of the inequalities do not intersect.

Hence, the set of inequalities do not have a solution
