Answer:
0.3
Step-by-step explanation:
x is the number to be added to 0.7 to have a sum of 1.
![0.7 + x = 1](https://tex.z-dn.net/?f=0.7%20%2B%20x%20%3D%201)
![x = 1 - 0.7](https://tex.z-dn.net/?f=x%20%3D%201%20-%200.7)
![x = 0.3](https://tex.z-dn.net/?f=x%20%3D%200.3)
Answer: e. Substitution Property
g. Substitution Property
Step-by-step explanation:
Answer:
![\displaystyle F(b + 3) = b^2 + 4b + 7](https://tex.z-dn.net/?f=%5Cdisplaystyle%20F%28b%20%2B%203%29%20%3D%20b%5E2%20%2B%204b%20%2B%207)
Step-by-step explanation:
We are given the function:
![\displaystlye F(x) = x^2 - 2x + 4](https://tex.z-dn.net/?f=%5Cdisplaystlye%20F%28x%29%20%3D%20x%5E2%20-%202x%20%2B%204)
And we want to find F(<em>b</em> + 3).
We can substitute:
![\displaystyle F(b + 3) = (b + 3)^2 - 2(b+3) + 4](https://tex.z-dn.net/?f=%5Cdisplaystyle%20F%28b%20%2B%203%29%20%3D%20%28b%20%2B%203%29%5E2%20-%202%28b%2B3%29%20%2B%204)
Expand:
![\displaystyle = (b^2 + 6b + 9) + (-2b -6) + 4](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%3D%20%28b%5E2%20%2B%206b%20%2B%209%29%20%2B%20%28-2b%20-6%29%20%2B%204)
Rearrange:
![\displaystyle = (b^2) + (6b-2b) + (9 - 6 + 4)](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%3D%20%28b%5E2%29%20%2B%20%286b-2b%29%20%2B%20%289%20-%206%20%2B%204%29)
Combine like terms. Hence:
![\displaystyle = b^2 +4b + 7](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%3D%20b%5E2%20%2B4b%20%2B%207)
In conclusion:
![\displaystyle F(b + 3) = b^2 + 4b + 7](https://tex.z-dn.net/?f=%5Cdisplaystyle%20F%28b%20%2B%203%29%20%3D%20b%5E2%20%2B%204b%20%2B%207)
