Answer:
383 children and 361 adults
Step-by-step explanation:
Let's say there are a adults and c children. Since the total number of people was 744, we can write:
a + c = 744
We also know that children's prices are $1.75 per child and adults' prices are $2 per adult. Since the total is $1392.25, we can write:
1.75c + 2a = 1392.25
Now we have a system of linear equations:
a + c = 744
1.75c + 2a = 1392.25
Multiply the first equation by 2:
2 * (a + c = 744) ⇒ 2a + 2c = 1488
Now subtract the second equation from this one:
2a + 2c = 1488
- 2a + 1.75c = 1392.25
___________________
0a + 0.25c = 95.75
c = 383
Plug this in to find a:
a + c = 744
a + 383 = 744
a = 361
There were 383 children and 361 adults.
Domain is the numbers you can use
see we have rom x<-3 and x≥-3
therefor it is all real numbers for the domain
domain=all real numbers
and the range is the output
for all numbers less than -3, we have x+4, so -10+3=-7, so it extends infinetely in negative direction
and for x^2+6, you start with -3 which ends with (-3)^2+6=9+6=13, after that it gets bigger
so therefor the range is
from -∞ to -7, not including -7 and from 13 to positive infinity
in interval notation
(-∞,-7)U[13,∞)
domain=all real number
range=(-∞,-7)U[13,∞) or all real numbers except all numbers c, such that -7≤c<13
