Step-by-step explanation:
- in order to know if the the point is on the line plug in the x coordinate to check if it gives you the y coordinate as an output.
- If you plug in the x coordinate and it gives you the given y coordinate then the point is on the given line
- Now let us plug in the value of x=-3
- now if you check plugging in the given x coordinate it does not give you the given y coordinate but -2
- therefore the point(-3,7) is not in the line but (-3,-2) is the point in the line.
The solution of the given compound inequality, 2x − 5 > 3 or 4x + 7 < −25, is <u>x < -8 or x > 4</u>. The graph of the inequality is attached.
In the question, we are asked to solve each compound inequality and graph the solution: 2x − 5 > 3 or 4x + 7 < −25.
We first solve each inequality separately as follows:-
1. 2x - 5 > 3,
or, 2x > 3 + 5,
or, 2x > 8,
or, x > 8/2,
or, x > 4.
2. 4x + 7 < - 25,
or, 4x < - 25 - 7,
or, 4x < - 32,
or, x < -32/4,
or, x < - 8.
Thus, the solution of the given compound inequality is x < -8 or x > 4.
Thus, the solution of the given compound inequality, 2x − 5 > 3 or 4x + 7 < −25, is <u>x < -8 or x > 4</u>. The graph of the inequality is attached.

The provided question is incorrect. The correct question is:
"Solve each compound inequality and graph the solution: 2x − 5 > 3 or 4x + 7 < −25".
The function g(x) factors as
g(x) = (x-4)(x-6)
so the x-intercepts are at x=4 and x=6.
The appropriate choice is
(4, 0) and (6, 0)
g(x) = (x-4)(x-6)
so the x-intercepts are at x=4 and x=6.
The appropriate choice is
(4, 0) and (6, 0)
