Answer:

Step-by-step explanation:
we know that
The probability that a point chosen randomly inside the rectangle is in the square is equal to divide the area of the square by the area of rectangle
Let
x-----> the area of square
y----> the area of rectangle
P -----> the probability

<em>Find the area of square (x)</em>

<em>Find the area of rectangle (y)</em>

Find the probability P

Answer: 
Explanation:
Follow PEMDAS in reverse to undo what's happening to x.
We first add 1 to both sides, then divide both sides by 5 to fully isolate x.
Refer to the steps below to see what I mean.

The inequality sign stays the same the entire time. The only time it flips is when you divide both sides by a negative number.
The solution set for x is anything -3 or larger.
If x was an integer, then we could say the solution set is {-3, -2, -1, 0, 1, 2, 3, 4, 5, 6, ...}
