Answer:
The answer to your question is 10 children and 4 adults
Step-by-step explanation:
Data
Adult cost = a = $11
Children cost = c= $7.50
Total people = 14
Total cost = $119
Number of adults and children = ?
Process
1.- Write two equations to solve this problem
a + c = 14 ----------- l
11a + 7.5c = 119 ----------- ll
2.- Solve the equations by elimination
Multiply equation I by -11
- 11 a - 11c = -154
11a + 7.5c = 119
0 -3.5c = -35
c = -35/-3.5
c = 10
3.- Find a
a + 10 = 14
a = 14 - 10
a = 4
4.- Conclusion
The group bought 4 tickets for adults and 10 tickets for children.
Present value, P = 20
compounding interest per 6 months, i = 0.025/2 = 0.0125
Number of periods, n = 30*2 = 60 (half-years)
Future value in 30 years
=P(1+i)^n
=20(1.0125)^60
= $42.14
Answer:
Multiply each term in the second equation by 2
Step-by-step explanation:
We have a system of equations that are wanted to be solve through elimination, which would be adding/subtracting the two systems of equations together and finding a variable. Knowing that, we need to find a way to cancel out one of the variables in the system of equation, which in this case is the lower value, y. So looking at both equations, we see we have -2y and y, to get y to 2y, we would need to multiply it by 2. But we can't leave that alone, we would have to multiply each term in the second equation by 2. Therefore giving us the answer.
Answer:
4. Domain: -3,-2,-1,0,1, and 2. Range: -2,0,2,4,2,0. It is a function
5. Domain: -3,-1,-1,1, 2,3 Range: 0,-1,2,0,-3,3. Not a function.
Step-by-step explanation:
Number four is a function because there is one x to one y but for five there are two x's to one y.
