Y intercepts: (0, 4)
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.
I = $125, r = 6% = 0.06, t = 1 year
I = prt
prt = I
p = I/rt
p = 125/(0.06*1)
P ≈ $2083.33
Answer:
[1, 2.5]
Step-by-step explanation:
A rate of change on x- axis is defined as positive if the function increases as x does, and defined negative if y decreases as x increases.
Thus, we only need to see in which of those intervals [–2, –1] , [–1.5, 0], [0, 1]. [1, 2.5] the graph of the function goes only down if we look it from left to right.
The only one interval satisfying this condition is [1, 2.5].
