Midpoint Formula: (
![\frac{x+x}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%2Bx%7D%7B2%7D%20)
,
![\frac{y+y}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7By%2By%7D%7B2%7D%20)
)
Midpoint = (
![\frac {-4+7}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%20%7B-4%2B7%7D%7B2%7D%20)
,
![\frac {-3-5}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%20%7B-3-5%7D%7B2%7D%20)
)
Midpoint = (
![\frac {3}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%20%7B3%7D%7B2%7D%20)
,
![\frac {-8}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%20%7B-8%7D%7B2%7D%20)
)
Midpoint = (
![\frac {3}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%20%7B3%7D%7B2%7D%20)
, -4)
So, the midpoint of the endpoints (-4,-3) and (7,-5) is (
![\frac {3}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%20%7B3%7D%7B2%7D%20)
, -4).
Have a nice day! ♪
1. 12=x+3 12-3=9 now try 9+3 that is 12 so x=9
2. b+0.6=-1 -1-0.6=-1.6 -1.6+0.6=-1 b=-1.6
3. a=-9
4. x=-39 I believe
5. a=-4.3
Answer:
x=-1/2
Step-by-step explanation:
-6x-7=4x-2
-6x-7+6x=4x+6x-2
-7=10x-2
-7+2=10x-2+2
-5=10x
-5/10=10x/10
x=-1/2
Hope this helps!
Answer:
<u>B</u>
Step-by-step explanation:
If a population is the entire school faculty, a sample of the population could be math teachers.
Always remember a sample is a part of the larger group.
Answer:
A 4/5 × 10 1/2 =8.4
B 2 1/2 × 16/5 =8
C 3 2/3 × 2 1/2 = 330/36 = 9.1666
D 20/3 × 9/10 =6
C IS THE GREATEST because 9.166 is greater than 8.4, 8 and 6
