Solution
It seems like you're working with two inequalities for :
To solve or visualize these inequalities, we can treat them as lines and then shade the region that satisfies both conditions.
Step 1: Graphing the Inequalities
Let's break down the lines these inequalities represent:
- The first inequality corresponds to the line , which has a slope of and a y-intercept of .
- The second inequality corresponds to the line , which has a slope of and a y-intercept of .
Step 2: Finding the Intersection Point
To find where these two lines intersect, we set the equations equal to each other:
Multiplying through by 5 to eliminate the fraction:
Now, solve for :
Now, substitute back into either equation to find :
Using :
So the two lines intersect at the point .
Step 3: Shading the Region
- For , shade the region above the line .
- For , shade the region above the line .
The solution to the system of inequalities will be the region above both lines, including the lines themselves.
