Answer:
30 seats
Step-by-step explanation:
To answer this question, we will be assigning values for both rows and seats.
R = Rows
S = Seats
Remember that rs = 600
r = s - 10, plug this equation into rs = 600, and factor it:
s(s-10) = 600
s^2-10s-600 = 0
(x-30)(x+20) = 0
There are 30 seats in the row. To determine which one is your answer, your answer MUST be positive because it is impossible to have negative seats. (x-30) is 30, which is the positive value found when factoring.
Answer: A
Step-by-step explanation:
Well when x is -1, y = 0, then when x is 0, y = 3 so it is increasing there...then when x is 1, y = 6, so it is still increasing, but then it goes back down to 3 when x is 2
Therefore, the largest interval would be from -1 to positive 1 (-1,1)
Hope this helps

Answer:
r = -2
Step-by-step explanation:
−88=11(r−6)
-88 = 11r -66
11r =-88+66
11r = -22
r = -2
