Answer: THE GRAPH IS ATTACHED.
Step-by-step explanation:
We know that the lines are:
Solving for "y" from the first line, we get:
In order to graph them, we can find the x-intercepts and the y-intercepts.
For the line the x-intercepts is:
And the y-intercept is:
For the line the x-intercepts is:
And the y-intercept is:
Now we can graph both lines, as you can observe in the image attached (The symbols and
indicates that the lines must be dashed).
By definition, the solution is the intersection region of all the solutions in the system of inequalities.
By definition, the perimeter of a square is given by:
Where,
L: length of the sides of the square.
When the sides of the square are tripled, the equation changes as follows:
Then, rewriting the equation we have:
Where,
P: perimeter of the original square.
Therefore, we can conclude that the perimeter is tripled.
Answer:
The perimeter of the square is tripled.
