These are easy, we just have to average the corresponding coordinates.
First we do a few one dimension ones, the midpoint of points on a number line:
1. 9 & 6
![\dfrac{9 + 6}{2} = \dfrac{15}{2}](https://tex.z-dn.net/?f=%5Cdfrac%7B9%20%2B%206%7D%7B2%7D%20%3D%20%5Cdfrac%7B15%7D%7B2%7D)
2. -2 & 7
![\dfrac{-2 + 7}{2} = \dfrac{5}{2}](https://tex.z-dn.net/?f=%5Cdfrac%7B-2%20%2B%207%7D%7B2%7D%20%3D%20%5Cdfrac%7B5%7D%7B2%7D)
3. -3 & -13
![\dfrac{-3 + -13}{2} = -8](https://tex.z-dn.net/?f=%5Cdfrac%7B-3%20%2B%20-13%7D%7B2%7D%20%3D%20-8)
For the rest of these we're in 2D, the Cartesian plane.
4. (0,0), (9,3)
![\left( \dfrac{0+9}{2}, \dfrac{0+3}{2} \right) = ( \frac 9 2, \frac 3 2)](https://tex.z-dn.net/?f=%5Cleft%28%20%5Cdfrac%7B0%2B9%7D%7B2%7D%2C%20%5Cdfrac%7B0%2B3%7D%7B2%7D%20%5Cright%29%20%3D%20%28%20%5Cfrac%209%202%2C%20%5Cfrac%203%202%29)
5. (-2,1), (3,6)
![\left( \dfrac{-2+3}{2}, \dfrac{1+6}{2} \right) = ( \frac 1 2, \frac 7 2)](https://tex.z-dn.net/?f=%5Cleft%28%20%5Cdfrac%7B-2%2B3%7D%7B2%7D%2C%20%5Cdfrac%7B1%2B6%7D%7B2%7D%20%5Cright%29%20%3D%20%28%20%5Cfrac%201%202%2C%20%5Cfrac%207%202%29)
6. (-3, 14), (10, -4)
![\left( \dfrac{-3+10}{2}, \dfrac{14+-4}{2} \right) = ( \frac 7 2, 5)](https://tex.z-dn.net/?f=%5Cleft%28%20%5Cdfrac%7B-3%2B10%7D%7B2%7D%2C%20%5Cdfrac%7B14%2B-4%7D%7B2%7D%20%5Cright%29%20%3D%20%28%20%5Cfrac%207%202%2C%205%29)
Answer:
The slope is equal to zero
Step-by-step explanation:
we know that
The formula to calculate the slope between two points is equal to
we have
substitute the values in the formula
so
The line passing for the given points is a horizontal line (parallel to the x-axis)
The slope is equal to zero
90,000
the reason is because look at the 1,000 place that rounds the 10,000 place to 0 and carries the 1 over to the 100,000 place
Answer:
ITs C One solution
Step-by-step explanation:
Two sides are not equal.
The simple interest on x dollars at 5-percent annual rate for 2 year is $0.1x
<h3>Calculating simple interest</h3>
The formula for calculating the simple interest is expressed as:
SI = PRT
where
P is the principal = $x
R is the rate = 5%= 0.05
Time T = 2 years
Substitute
SI = x * 0.05 * 2
SI. = 0.1x
Hence the simple interest on x dollars at 5-percent annual rate for 2 year is $0.1x
