12/x + 7 =13/x, where x is not 0;
<=> 12 + 7x = 13 <=> 7x = 1 <=> x = 1/7;
Changing the 30 to 10 is a 20 unit drop ( 30-10=20)
so the line would shift vertically down by 20
<span>The line will shift vertically down by $20.</span>
This is the concept of inequalities:
maximum capacity for the theater=425
Number of people in the theater=50
thus the inequality for the that will represent the number p of additional people who can be seated will be:
50+p≤425
hence:
p≤(425-50)
p≤375
Answer: p≤375
Answer:
