Answer:

The coordinates of the midpoint of the two vertices are

(0,2) (Third option)

Step-by-step explanation:

<u>Coordinates Of A Midpoint </u>

Given a pair of points in the plane

\displaystyle P_1\ (x_1,y_1)\ ,\ P_2(x_2,y_2)

the coordinates of the midpoint of both points are

\displaystyle x_m=\frac{x_1+x_2}{2}

\displaystyle y_m=\frac{y_1+y_2}{2}

The vertices given in the figure are  

\displaystyle v_1(-4,1),\ v_2\ (4,3)

So the x-coordinate of their midpoint is

\displaystyle x_m=\frac{-4+4}{2}=\frac{0}{2}=0

And the y-coordinate of their midpoint is

\displaystyle y_m=\frac{1+3}{2}=\frac{4}{2}=2

So the coordinates of the midpoint of the two vertices are

(0,2), the third option

The size of Texas is approximately 270000 square miles this ever represented approximately 41% of the size of Alaska approximate
Tanzania [10]
Let's set up the problem. First, we know Texas is 270,000 square miles, and this is 41% the size of Alaska.
So 270,000=41%(size of Alaska), or 270,000=.41(x). Now solve for x to find the size of Alaska.

Exercise<br>1<br>Solve the inequality<br>of these equation<br>pretty please ​
Ad libitum [116K]

Answer:

y<6

Step-by-step explanation:

1 /3 y +  1/4  >  3 /8y

1 /3 y +  1/4  −  3/ 8 y > 3/ 8 y −  3/ 8 y

− 1 /24 y +  1 4  > 0

−1 /24 y +  1 /4  −  1/ 4  > 0 −  1 /4

−1 /24 y >  −1/ 4

Multiply both sides by 24/(-1).

y<6

Planet ruba has a population of 1 million alien planet Zamba has one hundred thousand million how many more aliens does planet r
Elena-2011 [213]
Let's put it into numbers:

Ruba: 1 000 000

Zamba: 100 000 000 000

Zamba has many more aliens than Ruba!!!

it has 100 000 000 000/1 000 000 =100 000 times more aliens,

in absolute numbers: 100 000 000 000 - 1000 000 =  =99 999 900 000

100 000 000 000
           - 100 000
=99 999 900 000
