The last one! Because every input has to have a different output! And the last one all have different output compared to the other ones that have the same output with different inputs which does not represent a function
Answer:
16
Step-by-step explanation:
2(9x + 3) + 5x = 48 + 2x
18x + 6 + 5x = 48 + 2x
23x + 6 = 48 + 2x
23x - 2x = 48 - 6
21x = 42
x = 42/21
x = 2
Expression: 6 × -2
Solution: -12 degrees Fahrenheit
Answer:
1 5/9
Step-by-step explanation:
9 1/3 can be rewritten as 28/3. The question is asking for you to divide 28/3 by 6. 6 is 6/1, so the expression is 28/3 divided by 6/1. You then do the reciprocal of 6/1 and the expression is 
. This gets you 28/18, which is simplified to 14/9 or 1 5/9. Hope this helps!
