Answer:
(9.2 , 0)
Step-by-step explanation:
vertex: (4.6 , 12.2)
parabola: y = a (x-4.6)² + 12.2
pass (0,0): 0 = a (0-4.6)² + 12.2
a = - (12.2/21.16)
2nd root (x , 0): y=0
0 = a (x-4.6)² + 12.2 (x-4.6)² = - 12.2 / a = -12.2 / (- (12.2/21.16)) = 21.16
x - 4.6 = ± √21.16 = ± 4.6
x = 0 or x = 9.2
Answer:
FALSE
Step-by-step explanation:
246=2*3*41
If n=2 then 123=3*41 is not a multiple of n
FALSE
1. Expand the equation
−7 + 56i + 4i +32
2. Gather like terms
(−7 + 32) + (56i + 4i)
3. Simplify
25 + 60i
The correct answer would be D. 25 + 60i

Hello!</h2>
The answer is:
A.
![h(x)=9x-13](https://tex.z-dn.net/?f=h%28x%29%3D9x-13)
<h2>Why?</h2>
To solve the problem, we need to perform the shown operation.
We have the functions:
![f(x)=2x-1\\g(x)=7x-12](https://tex.z-dn.net/?f=f%28x%29%3D2x-1%5C%5Cg%28x%29%3D7x-12)
So, performing the following operation, we have:
![f(x)+g(x)=h(x)](https://tex.z-dn.net/?f=f%28x%29%2Bg%28x%29%3Dh%28x%29)
![h(x)=f(x)+g(x)=(2x-1)+(7x-12)=7x+2x-1-12=9x-13](https://tex.z-dn.net/?f=h%28x%29%3Df%28x%29%2Bg%28x%29%3D%282x-1%29%2B%287x-12%29%3D7x%2B2x-1-12%3D9x-13)
![h(x)=9x-13](https://tex.z-dn.net/?f=h%28x%29%3D9x-13)
Hence, we have that the correct option is:
A. ![h(x)=9x-13](https://tex.z-dn.net/?f=h%28x%29%3D9x-13)
Have a nice day!
