Answer:
5
Step-by-step explanation:
To evaluate (g ○ h)(9), evaluate h(9) , then use this value to evaluate g(x)
h(9) =
= 3, then
g(3) = 2(3) - 1 = 6 - 1 = 5
C is FALSE
the set of whole numbers is { 0, 1, 2, 3, 4 , ......}
the set of integers is { ..., - 2, - 1, 0, 1, 2, 3, ......}
As we can see the set of whole numbers does not include negative numbers, thus integers are not a subset of whole numbers
However, whole numbers are a subset of integers.
Answer: in explanation
Step-by-step explanation
Sandi can perform 1/9 of the task in a day
Eva can perform 1/5 of the task in a day
Working together, they can perform
1/9 + 1/5 of the task per day
= 5/45 + 9/45 = 14/45 of the task in a day
or 45/14 days in the task = 3.2 days
So
It would take about 3.2 days to complete the task working togethe
F(-1) = 3
How did I figure this out?
f(-1) is substituted for f(x) so you must look at -1 on the x axis.
Once you've located -1 on the x-axis, locate what it equals to answer the question.
The answer should be the y-axis number that corresponds to -1 which is 3.
