Answer:
![(f+g)(x) = x^2 + 4x - 4](https://tex.z-dn.net/?f=%28f%2Bg%29%28x%29%20%3D%20x%5E2%20%2B%204x%20-%204)
Step-by-step explanation:
We are given these following functions:
![f(x) = 4x + 2](https://tex.z-dn.net/?f=f%28x%29%20%3D%204x%20%2B%202)
![g(x) = x^2 - 6](https://tex.z-dn.net/?f=g%28x%29%20%3D%20x%5E2%20-%206)
(f+g)(x)
We add the common terms. Thus:
![(f+g)(x) = f(x) + g(x) = 4x + 2 + x^2 - 6 = x^2 + 4x + 2 - 6 = x^2 + 4x - 4](https://tex.z-dn.net/?f=%28f%2Bg%29%28x%29%20%3D%20f%28x%29%20%2B%20g%28x%29%20%3D%204x%20%2B%202%20%2B%20x%5E2%20-%206%20%3D%20x%5E2%20%2B%204x%20%2B%202%20-%206%20%3D%20x%5E2%20%2B%204x%20-%204)
Thus:
![(f+g)(x) = x^2 + 4x - 4](https://tex.z-dn.net/?f=%28f%2Bg%29%28x%29%20%3D%20x%5E2%20%2B%204x%20-%204)
Equation A (y=mx + b) is in slope intercept form.
<span>Let the nickels be x and the dimes be y
x + y = 24
5x + 10y = 185
5x + 5y = 120
5y = 65
y=13
x=11
Answer: 11 nickels and 5 dimes</span>
Answer:
a
Step-by-step explanation:
divide 9 and 6 each by 3 and bam you got a 2x3 poster
Well actually depending on the size, if a small one I would use liters, but if a large ones like Olympics I would use kilolitres.
