The sum of twice a number n and 8 is at most 25

This is an inequality because it is stating that the answer is at most 25. This means that the answer can be anything below and including 25, so the ≤ sign is needed.Tthis inequality can then be shows with the following inequality equation:

2n + 8 ≤ 8  

Because 2n shows that the n is multiplied twice ( or the sum of twice a number n) and the + 8 shows the added 8.

Step-by-step explanation:

Hope this helps you

the answer is 8

step-by-step explanation:

3.14 x 8x8

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
