Is the function x=-1y+8 if so that can be changed to: y=-x+8. Then this is just a simple line and the y intercept is (0,8) and the x intercept is (8,0). Those are two points on the graph other points are (1,7) (2,6) (3,5) etc....
I suppose you have to find the four numbers. If
![x](https://tex.z-dn.net/?f=x)
is the smallest of the four, then the next three numbers are
![x+2](https://tex.z-dn.net/?f=x%2B2)
,
![x+4](https://tex.z-dn.net/?f=x%2B4)
, and
![x+6](https://tex.z-dn.net/?f=x%2B6)
. The mean is 15, so
![\dfrac{x+(x+2)+(x+4)+(x+6)}4=\dfrac{4x+12}4=15](https://tex.z-dn.net/?f=%5Cdfrac%7Bx%2B%28x%2B2%29%2B%28x%2B4%29%2B%28x%2B6%29%7D4%3D%5Cdfrac%7B4x%2B12%7D4%3D15)
![\implies x+3=15](https://tex.z-dn.net/?f=%5Cimplies%20x%2B3%3D15)
![\implies x=12](https://tex.z-dn.net/?f=%5Cimplies%20x%3D12)
So the four numbers are 12, 14, 16, and 18.
Answer:
6.25 inches
Step-by-step explanation:
3/4 inches = 0.75 inches
If 0.75 inches is the map's scale for 3 miles, then:
0.75 inches / 3 miles = 0.25 inches per 1 mile
Multiply 0.25 inches inches per mile * 25 miles:
0.25 * 25 = 6.25 inches
OR:
0.75/3 = x/25
Multiply 25 by both sides:
x = (0.75/3)*25
x = 6.25 inches
Which pair of angles are vertical angles?
∠AOE and ∠COD
Answer:
The first one
Step-by-step explanation:
the first one is biased because it is not random but rather people who are using the library. They will obviously be biased towards the library
