Place the x values (if there are two of the same x value you only include it once) in the first box vertically like:
5
-3
6
2
Place the y values (if there are two of the same y values only include it once) in the 2nd box vertically like:
1.2
7
-3
Now draw lines from your x values to their corresponding y values.
A function may NOT have two y-values assigned to the same x-value, but it may have two x-values assigned to the same y-value.
So this is a function!
Answer:

Step-by-step explanation:
We are given

we can rewrite it as

we know that
2y^2+7y-7 can not be factored
so, we can not reduce this expression
because this is the only way to reduce it
so, we get reduced form as

$45 x .15 = 6.75
This is the amount that she saved
$45 - 6.75 =
The amount that she still needs to save.
Answer:
10p because when a number is with a letter its always multipucation
like 11x = 11x1
Answer:
60
Step-by-step explanation:
Assuming that all 54 shelves hold the same number of books its just a matter of dividing them (or sharing them equally) on each shelf.
3240 / 54 = 60
Each shelf holds 60 books.
