The graphed system of inequalities is:
- y ≥ x^2 - 2x - 3
- y ≤ x + 3
So the correct option is the third one.
<h3>Which system is represented by the graph?</h3>
On the graph we can see that the two lines are solid, so we need to use the symbols ≤ and ≥. (If instead, we had dashed lines, then we would need to use the symbols > and <).
We also can see that the region above the parabola is shaded (the shaded region represents the region of solutions for each inequality), and the region below the line is shaded, then the system of inequalities is of the form:
Only with that, we conclude that the correct option is the third option:
- y ≥ x^2 - 2x - 3
- y ≤ x + 3

Answer:
2x-3y=20
12x+8y=-192
Solution
In the determinant of the matrix to find the variable "x" [Ax], we replace the coefficients of "x" (2 and 12) by the independent terms (20 and -192 respectively).
In the determinant of the matrix to find the variable "y" [Ay], we replace the coefficients of "y" (-3 and 8) by the independent terms (20 and -192 respectively).
This is an example of the
difference of squares.
So to find the product of <span>(9y</span>²<span> – 4x)(9y</span>²<span> + 4x), we use the formula for the difference of squares.
