PLEASEEEE HELP DUE TODAY! MIGHT GIVE BRAINLIST! EFOORT WILL BE RESPECTED! PIC ATAACHED
1 answer:
The attached image represents the interval 2 < x ≤ 9 on the number line
<h3>How to highlight the interval?</h3>The interval is given as:
2 < x ≤ 9
The above interval means that:
- 2 is exclusive of the values of x (because of the < inequality symbol)
- 9 is inclusive of the values of x (because of the ≤ inequality symbol)
In inequality, the < symbol uses an open circle, while the ≤ uses a closed circle
Next, we highlight the interval using the above rules (see attachment)

Answer:
Explanation:we will solve this question with help of linear programming.
Now, let Ben goes x times in buffalo trip and goes y times in Philadelphia trip. Thus, according to the question, Min Z= 180x+300y
And s.t.r. 2x+3y≤105, where x≥5, y≥15.
since at (0,0) 0≤105(true), so area of 2x+3y≤105 will cover the origin.
But, 0≥5 and 0≥15 are false, so their area will not cover the origin.
Thus, after drawing the graph of these three lines we will get a feasible reason of triangle ABC, where point A≡(5,31.667), B≡(5,15), and C≡(30,15)
Z at A- 180×5+300×31.667=10,400.1
at B-180×5+300×15=1350( which is minimum.)
at C- 180×30+300×15=5,850
Thus, Ben should go 5 times to buffalo trip and 15 times to Philadelphia to minimize his cost which is $1350.
