The possible combinations of adult tickets and children tickets are : (0, 10), (1, 8), (2, 6), (3, 4), (4, 2), (5, 0)

<u><em>Explanation</em></u>

Suppose, the number of adult tickets is x and the number of children tickets is y

Given that, adult tickets cost 4 and children tickets cost 2 and Natalie sold 20 worth of tickets. So the equation will be.....

4x+2y=20\\ \\ 2y= 20-4x\\ \\ y= 10-2x

If x = 0, then y= 10-2(0)= 10

If x = 1 , then y= 10-2(1)= 8

If x = 2 , then y= 10-2(2)= 6

If x = 3 , then y= 10-2(3)= 4

If x = 4 , then y= 10-2(4)= 2

If x = 5 , then y= 10-2(5)= 0

If we take x value greater than 5 , then y will become negative which is not possible.

So, the possible combinations of adult tickets and children tickets are : (0, 10), (1, 8), (2, 6), (3, 4), (4, 2), (5, 0)

If anyone could help out with this one i would really appreciate it <br><br> f(2)=?
algol13

Answer:

f(2) = 0

Step-by-step explanation:

Function f(t) is defined in three different ways depending on the value of t.

For t = 8, function f(t) is -64/t.

For t = 10, function f(t) is 14 - t.

We are not asked about f(8) or f(10). We are asked about f(2). The third definition of function f(t) is for all values of t that are not 8 or 10. 2 is not 8 or 10, so use the third definition of function f(t) and plug in 2 for t.

f(t) = t^2 - 3t + 2 for t not equal to 8 or 10.

f(2) = 2^2 - 3(2) + 2

f(2) = 4 - 6 + 2

f(2) = 0
