It does. Because 6+(-1) equals 5 and so does 19-14
Answer:
x = 1± 3i
Step-by-step explanation:
x^2-2x+10=0
We can complete the square to solve by subtracting 10 from each side
x^2-2x+10-10=-10
x^2 -2x = -10
We need to add (2/2) ^2 to each side or 1
x^2 -2x+1 = -10 +1
x^2 -2x+1 = -9
The left side factors into (x- (2/2) ) ^2
(x-1) ^2 = -9
Take the square root of each side
sqrt((x-1) ^2 =± sqrt(-9)
x-1 = ±sqrt(-1) sqrt(3)
Remember the sqrt(-1) = i
x-1 = ± 3i
Add 1 to each side
x-1+1 = 1± 3i
x = 1± 3i

Answer:
See attachment for graph
Step-by-step explanation:
Given
![1\ hr = 10\ miles](https://tex.z-dn.net/?f=1%5C%20hr%20%3D%2010%5C%20miles)
Required
The graph that shows the number of miles in x hours
We have:
![1\ hr = 10\ miles](https://tex.z-dn.net/?f=1%5C%20hr%20%3D%2010%5C%20miles)
Multiply both sides by x
![x * 1hr = 10miles * x](https://tex.z-dn.net/?f=x%20%2A%201hr%20%3D%2010miles%20%2A%20x)
![xhr=10x\ miles](https://tex.z-dn.net/?f=xhr%3D10x%5C%20miles)
So, the function is:
![f(x) =10x](https://tex.z-dn.net/?f=f%28x%29%20%3D10x)
