To find a solution that satisfies the inequalities
-
Graph the inequalities:
-
For
:- This is a line with a slope of 4 and a y-intercept of -2. The area below this line represents the solutions for this inequality (since it is a "less than" inequality).
-
For
:- This is a line with a slope of -
and a y-intercept of 2. The area below this line, including the line itself, represents the solutions for this inequality (since it is a "less than or equal to" inequality).
- This is a line with a slope of -
-
-
Find the intersection point: To find where both inequalities are satisfied, we can first find the intersection of the two lines:
Multiply the entire equation by 3 to eliminate the fraction: Rearranging gives:Now, substituting
back into either equation to find : Using :Thus, the intersection point is
. -
Determine if it's a solution: Now, choose points around this intersection to check which satisfies both inequalities. Let's take the point
to see if it fits:-
For
: (True)
-
For
: (True)
-
Thus, the point (1, 0) is a solution to the system of inequalities.
So, one of the solutions would be:
