Answer:
The greatest number of arrangements possible would be 5
Step-by-step explanation:
If we look at the x values (in this case # of tulips remaining) we can find the number 20. And we see that there is a line going through it. We then stop at the point and go down to see what number it would fall on on the y axis.
Answer:
c) 2(2y+1)
Step-by-step explanation:
This is because when the tables are together there can be 4 people at each table, plus 1 at either end. Whatever equation you have must have +2 in it, to account for the ends of the tables. The number of tables (y) must be multiplied by 4 because there are always 4 people per table. The number of tables is unknown so 4y must be in your equation.
2(2y+1) simplifies to 4y+2, which is the equation we want.
I’m pretty sure the answer is A.
