The only order pairs among the given options that represent a function is :
Because : To be a function, every element of domain (x) can have only one unique value y, and if we get more than two values of y for same x, it isn't a function at all.
n = 2
distribute and simplify left side of equation
50 - 10n - 1 = 29
49 - 10n = 29 ( subtract 49 from both sides )
- 10n = 29 - 49 = - 20
n = = 2
Answer:
12 hours
Step-by-step explanation:
Let the number of hours Lily works each week be x.
This implies that of Olivia's is
x+4.
We were also told that for every two weeks, Olivia works a total of 32 hours.
This implies that
2(x+4)=32
We divide through by 2
We subtract 4 from both sides
Hence Lily works 12 hours each week.
