Answer:
24.44%
Step-by-step explanation:
initial value :45
final value:56
change in value= 56-45=11
percentage change= 11
![\frac{11}{45} \times \frac{100}{1}](https://tex.z-dn.net/?f=%20%5Cfrac%7B11%7D%7B45%7D%20%20%5Ctimes%20%20%5Cfrac%7B100%7D%7B1%7D%20)
![\frac{1100}{45}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1100%7D%7B45%7D%20)
=24.44%
I am pretty sure its B (minimum at -1, -4) because that would be were the first point would be at. The Graphing of this equation would be a "upside down u" shape.
Answer:
AC = 30
Step-by-step explanation:
Start with:
![4x+10=3x-2+2x+7](https://tex.z-dn.net/?f=4x%2B10%3D3x-2%2B2x%2B7)
Combine like terms.
![4x+10=5x+5](https://tex.z-dn.net/?f=4x%2B10%3D5x%2B5)
Subtract
from both sides of the equation.
![10=x+5](https://tex.z-dn.net/?f=10%3Dx%2B5)
Subtract
from both sides of the equation.
![x = 5](https://tex.z-dn.net/?f=x%20%3D%205)
Then, substitute
for
in ![AC=4x+10](https://tex.z-dn.net/?f=AC%3D4x%2B10)
![AC=4(5)+10](https://tex.z-dn.net/?f=AC%3D4%285%29%2B10)
Multiply.
![AC=20+10](https://tex.z-dn.net/?f=AC%3D20%2B10)
Finally, add.
![AC=30](https://tex.z-dn.net/?f=AC%3D30)
Answer:5hours
