Point a is at (-7,-7) and m is at (-6,-1) what are the coordinates of point b
AlekseyPX

Answer:

The coordinates of point b are (-5,5).

Step-by-step explanation:

Given:

Point a is at (-7,-7) and m is at (-6,-1).

So, to find the coordinates of point b.

Let a (-7,-7) be (x_{1},y_{1}), m (-6,-1) and b (x_{2} ,y_{2}).

Now, putting the formula to get the coordinates:

m=\frac{x_{1}+x_{2}}{2} , \frac{y_{1}+y_{2}}{2}

⇒(-6,-1)=\frac{-7+x_{2}}{2} , \frac{-7+y_{2}}{2}

So, here we will make two equations to find the value of x_{2} andy_{2}:

-6=\frac{-7+x_{2}}{2}

multiplying both sides by 2

⇒-12=-7+x_{2}

⇒-5=x_{2}

And, now same method for getting the value of y_{2}.

-1=\frac{-7+y_{2}}{2}

multiplying both sides by 2

⇒-2=-7+y_{2}

⇒5=y_{2}.

The value of (x_{2} ,y_{2}) = (-5,5).

Therefore, the coordinates of point b are (-5,5).

Step-by-step explanation:

There is 2 Os and 8 in total.

So the probability of selecting O is 1/4

As the question asks everything but O, you subtract that answer from 1. 1-1/4=3/4
