Answer:

Carly multiply by -4 instead of dividing

Step-by-step explanation:

-4(7j+2) = 10

Divide each side by -4

-4/-4(7j+2) = 10/-4

7j+2 = -2.5

Answer:

Carly's mistake is in Step 1. She multiplied -4 and 10 instead of dividing -4 and 10

Step-by-step explanation:

-4(7j+2)=10

7j+2= -2.5

7j= -4.5

j= -0.643 or j = -4/7

The midpoint of QR is (4, -1).<br> Q = (3.1)<br> What are the coordinates of point R?

vitfil [10]

Answer:

(5,-3)

Step-by-step explanation:

Given that,

The coordinates of Q = (3,1)

The midpoint of QR = (4,-1)

We need to find the coordinates of point R.

We know that, according to mid-point theorem,

$(x_m,y_m)=(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})$

Let (x₂,y₂) be the coordinates of point R.

So,

$(4,-1)=(\dfrac{3+x_2}{2},\dfrac{1+y_2}{2})\\\\\dfrac{3+x_2}{2}=4\ and\ \dfrac{1+y_2}{2}=-1\\\\3+x_2=8\ and\ y_2+1=-2\\\\x_2=5\ and\ y_2=-3$

So, the coordinates of point R is (5,-3).

Val is at 200 Yards when Johnny stops for his friends.

You can see that because, at the same time (The Y-axis) that Johnny stops, Val is just at 200 yards
