K is the midpoint of PQ, P has coordinates (-9,-4), and K
has coordinates (-1, 6). What
are the coordinates of Q?
A (-5, 1) C (-11,8)
B (5, 10) D (7.16)

Coordinates of Q

Option D is correct option.

Step-by-step explanation:

We are given:

K is the midpoint of PQ

Coordinates of P = (-9,-4)

Coordinates of K = (-1,6)

We need to find coordinates of Q  

We will use the formula of midpoint:

We are given midpoint K and the coordinates of P we need to find the coordinates of Q.

Now, we can write

So, we get coordinates of Q

Option D is correct option.

d (5 x (-20)) * (100 x (0.7))

step-by-step explanation:

5÷1/100 * -.7 *-20

copy dot flip

5*100 * -.7 *-20

rearrange

5*-20   * 100 *-.7

-100   *-70
