The domain is {-9,-4,3,9} and the range is {2}.
Inserting 7 into the function, you get f(7)=2*7 which is 14. Therefore, someone can complete 14 guitar lessons in 7 months.
Answer:
- 11x
- 40=
- 51x
Step-by-step explanation:
you just add it
Answer:
Step-by-step explanation:
2x - 7 + 2x - 5 + 2x - 3 + 2x - 1 + 2x + 3 + 2x + 5 + 2x + 7 Combine like terms
16x / 8 = 48
2x = 48
x = 24
The range is defined as the largest number - the smallest number
The range is between 2x - 7 and 2x + 7
x = 24
The smallest number is 48 - 7 = 41
The largest number is 48 + 7 = 55
The range = 55 - 41 = 14
Why was the 2 in front of the x needed? It was to make sure that I could create an odd number.
Why did I subtract an odd number? That was to make sure that I could create odd numbers.
Why did I start with 2x - 7 and end up 8 terms later at 2x + 7?
So the numbers would cancel and I'd only be left with x's.
For number seven i got 1974m
and for number eight i got 374.13
