Answer:
x-y=2
I don't get why they are asking you what is 2-5. That seems super basic compared to the other question it is with. Since 5-2=3, then 2-5 or -5+2=-3.
Step-by-step explanation:
We are going to use identity x^2-y^2=(x-y)(x+y)
x^2-y^2=10
(x-y)(x+y)=10
(x-y)(5)=10
Since (2)(5)=10, this implies x-y=2.

<em>In total 5 days, she has paid: </em><em>$50 - $10 = $40 </em><em>for the comics</em>
<em>So, she paid: </em>$40 / 5 = $8<em> for each comic</em>

Answer:
The 4th one.
Step-by-step explanation:

Answer:
(-9, 10)
Step-by-step explanation:
The location of the midpoint of a line with endpoint at (
) and (
) is given as (x, y). The location of x and y are:

Given the endpoint (9,8) and Midpoint (0,9), the location of the other endpoint can be gotten from:

Hence the endpoint is at (x2, y2) which is at (-9, 10)
