There are 63 students in the room, this is because 21 time 3 gives you 63.
G(-3) = -3-7 = -10;
f(g(-3))=f(-10) = 2 x (-10) + 5 = - 20 + 5 = -15.
21k - 3n + 9p > 3p + 12....for n
-3n > 3p + 12 - 9p - 21k
n < (3p + 12 - 9p - 21k) / -3
n < -p - 4 + 3p + 7k
n < 2p - 4 + 7k <===
Answer:
Kindly check explanation
Step-by-step explanation:
Given that :
Balance prior to statement date = - 3.46
Minimum bank balance to avoid penalty = $10
The amount of deposit, d made in time in other to avoid penalty fee?
Minimum amount that most have been deposited, d :
Balance prior to statement + d ≥ minimum bank balance to avoid penalty
-3.46 + d ≥ 10
d ≥ 10 + 3.46
d ≥ 13.46
Hence, the minimum amount that must have been deposited to avoid penalty is 13.46
Elimination is x=3 since you can cancel our out the 3y just add the 8 and 2 which is 10 and 18 and 12 which is 30, devide and there ya go
