Answer:

A. 10/19

Step-by-step explanation:

The mean is 7.63, so 8,9, and 10 are above that. There are 9 that are either 8, 9, or 10. 19-9=10, therefore making the only possible answer 10/19

I hope this helps you :)

What is the image of (-8,2)(−8,2) after a reflection over the y-axis?
mars1129 [50]

Answer:

(8,2)

Step-by-step explanation:

The rule is (x,y) becomes (-x, y).  You can visualize this.  (-8,2) is 8 units to the left of the origin (0,0) and two units up from the origin (0,0).  Now, it we flip it so that is is on the other side of the y axis, it is still two units above the origin(0,0), but it is now 8 units to the right of the origin.

Subtract the rational expression 1/x^2-x-6 - x/x+2.
Aleksandr [31]

Answer:

Step-by-step explanation:

x² - x -6 = x²  + 2x - 3x - 3*2

            =x(x + 2) - 3(x + 2)

            = (x + 2 )(x - 3)

\frac{1}{x^{2}-x-6}+\frac{x}{x+2}=\frac{1}{(x +2 )(x - 3)}-\frac{x}{x + 2}\\

                      = \frac{1}{(x+2)(x-3)}-\frac{x(x-3)}{(x+2)(x-3)}\\\\=\frac{1-x(x-3)}{(x+2)(x-3)}\\\\=\frac{1-x^{2}+3x}{(x+2)(x-3)}\\\\
