A=10
B=500
I think this is write sorry if I’m wrong
Answer:
B. −x^2+2x+4
Step-by-step explanation:
(f-g)(x)
fx - g=
6x^2+4x−7−2x−7x^2+11
=6x^2+4x+−7+−2x+−7x^2+11
Combine Like Terms:
=6x^2+4x+−7+−2x+−7x^2+11
=(6x^2+−7x^2)+(4x+−2x)+(−7+11)
=−x^2+2x+4
Answer:
![x\geq 6\text{ or } x](https://tex.z-dn.net/?f=x%5Cgeq%206%5Ctext%7B%20or%20%7D%20x%3C-3)
Step-by-step explanation:
We have the compound inequality:
![2(x-1)\geq10\text{ or } 3-4x>15](https://tex.z-dn.net/?f=2%28x-1%29%5Cgeq10%5Ctext%7B%20or%20%7D%203-4x%3E15)
Let's solve each of them individually first:
We have:
![2(x-1)\geq10](https://tex.z-dn.net/?f=2%28x-1%29%5Cgeq10)
Divide both sides by 2:
![x-1\geq5](https://tex.z-dn.net/?f=x-1%5Cgeq5)
Add 1 to both sides:
![x\geq6](https://tex.z-dn.net/?f=x%5Cgeq6)
We have:
![3-4x>15](https://tex.z-dn.net/?f=3-4x%3E15)
Subtract from both sides:
![-4x>12](https://tex.z-dn.net/?f=-4x%3E12)
Divide both sides by -4:
![x](https://tex.z-dn.net/?f=x%3C-3)
Hence, our solution set is:
![x\geq 6\text{ or } x](https://tex.z-dn.net/?f=x%5Cgeq%206%5Ctext%7B%20or%20%7D%20x%3C-3)
The area of the figure is 806.
A= 806.5
