Answer:
y(x)=5x for (20≥x≤40)
Step-by-step explanation:
Step one :
Given data
Cost of ticket =$5
Given that the number of tickets to be sold for the tour to happen should be at least 20 and not more than 40
Step two :
Let the number of tickets be x
And let the revenue or income be y
The function for the cost is expressed linearly as
y(x)=5x
The domain is y(x)=5x for (20≥x≤40)
19 children tickets and 31 adults ticket were sold
2x+5y = 193
Step-by-step explanation:
sold 19 tickets for children $2 = 19×2 = $38
sold 31 tickets for adult $5 = 31×5 = $155
Total debut = $38 + $155 = $193
Total Seats = 19 (children)+ 31 adults) = 50 seats
2x+ 5y = 193 where x denotes children tickets and y denotes adult tickets
2(19)+5(31) =193
(2×19) + (5×31) = 38 + 155 = 193

The answer is <span>2n * (-1)^(n + 1)
</span><span>The numerator seems to be accelerated via 7 each and every time, so if it starts with the 1st term being one, it incredibly is secure to declare the nth numerator is 7^(n-a million) Likewise, the backside has a million, a million*2, a million*2*3, a million*2*3*4, and a million*2*3*4*5. This seems to be factorials, so we are in a place to declare the nth term interior the denominator is n! putting those mutually, the nth term is 7^(n-a million)/n!
</span>I hope this helped God Bless!
