Answer:
y = 75 - 9d
Step-by-step explanation:
y = amount of $ left
(f - g)(x) = (3x² + 1) - (1 - x)
= 3x² - x
OR
= x(3x - 1)
Answer:
1/18
Step-by-step explanation:
Assuming the die are regular 1,2,3,4,5,6
P(2) = number of 2's/ total numbers on die
= 1/6
Roll again
Assuming the die are regular 1,2,3,4,5,6
P (numbers greater than 4) = {5,6}/total numbers on die
=2/6 = 1/3
P (2, then number greater than 4) = 1/6 * 1/3 = 1/18
The price of one senior citizen ticket is 8$ and one student ticket is 12$.
<h3>What is the equation?</h3>
The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
Let the price of one senior citizen ticket = x
And the price of one student ticket = y
Given that, on the first day of ticket sales, the school sold 13 senior citizen tickets and 13 student tickets for a total of $260
The school took in $212 on the second day by selling 13 senior citizen tickets and 9 student tickets.
13x +13y = 260
13x + 9y = 212
Subtract the equation from first
13x +13y - (13x + 9y) = 260 - 212
4y = 48
y = 48/4
y = 12
Substitute the value of y in the equation 13x + 9y = 212
13x + 9(12) = 212
13x + 108 = 212
13x = 212 - 108
13x = 104
x = 104/13
x = 8
Hence, the price of one senior citizen ticket is 8$ and one student ticket is 12$.

Answer:
Step-by-step explanation:
The base case in the recursive function are:
The recursive case is equal to:
So replace 
for 
:
In the new expression 
is a base case so you don't have to worry for that part, but 
is still the recursive case so evaluate again in
and 
are define as base cases so you replace for it's numbers:
Now return to and replace for the new values:
So the final answer is 20
