Plug in -3n as n into the functon K(n)=4n+5
so you get
K(-3n)=4(-3n)+5
K(-3n)=-12n+5
Answer:
Yes, I cannot tell what it wants you to state if it is though.
Step-by-step explanation:
I am assuming you are familiar with coordinates representing x and y coordinates so (x,y). If this is unfamiliar let me know.
For a function, there cannot be a repeat of xs unless every one goes to the same y. So for instance if (3,4)(3,5) were in the list this would not be a function because 3 is used twice but goes to a different number each time.
If the list had (3,4) twice so (3,4)(3,4), that could still be a function.
In your list There are no repeating xs, so you don't even need to check. It is a function.

Answer:
66
Step-by-step explanation:
105+420=525 (Total Money)
7x3.25=22.75 (Cost of all bracelets)
8x11.74=93.92 (Cost of all necklaces)
93.92+22.75=116.67 (Cost of all Christmas presents)
525-116.67=408.33 (Total money - Cost of all Christmas presents)
408.33/6.15=66.39... (Amount of necklaces)
since in real life you can only buy a whole number of things, you would round down 66.39 to 66. I hope this helped!
