Answer:
D. x=1
Step-by-step explanation:
Image can be rewritten as 3x + 6 = 9.
Solve for x.
3x +6 = 9
Isolate x by subtracting 6 from both sides.
3x = 3
Get rid of the 3 by dividing by 3 on both sides.
x = 1
Hope this helped.
The mid point is 15 because it is in the middle of 10 and 20
47. You subtract the lowest number from the highest to get your range.
Answer:
![x^2-8x=0](https://tex.z-dn.net/?f=x%5E2-8x%3D0)
Step-by-step explanation:
the quadratic function should be as follows:
![x^2-8x=0](https://tex.z-dn.net/?f=x%5E2-8x%3D0)
Now let's confirm that the zeros of the function are 0 and 8
![x^2-8x=0=x(x-8)=0](https://tex.z-dn.net/?f=x%5E2-8x%3D0%3Dx%28x-8%29%3D0)
Therefore we can see that if x = 0
![0^2*8*0=0\\0=0](https://tex.z-dn.net/?f=0%5E2%2A8%2A0%3D0%5C%5C0%3D0)
the equation is fulfilled
And we also have ![(x-8)](https://tex.z-dn.net/?f=%28x-8%29)
for this expresion to be equal to zero:
![x-8=0\\x=8](https://tex.z-dn.net/?f=x-8%3D0%5C%5Cx%3D8)
thus, if x = 8
![8^2-8*8=0\\64-64=0\\0=0](https://tex.z-dn.net/?f=8%5E2-8%2A8%3D0%5C%5C64-64%3D0%5C%5C0%3D0)
the equation is also fulfilled
The zeros of the quadratic function
are 0 and 8.
