Answer:
x^2 - 10x + 25 = 17
Step-by-step explanation:
Please use " ^ " to denote exponentation:
x^2 - 10x = -8
x^2 - 10x + 25 = 17
x^2 - 10x + 25 = -8
x^2 - 10x - 25 = -33
Begin with x^2 - 10x = -8. Here's the process for completing the square:
1. Take half of the coefficient of x and square the result:
(1/2)(-10) = -5, and then (-5)^2 = + 25
2. Add this 25 to the first two terms of x^2 - 10x = -8 and also to the constant -8: x^2 - 10x + 25 = -8 + 25, or x^2 - 10x + 25 = 17
3. Match this result to one of the given possible answers. Turns out that the given possible answer matching our result is the first one:
x^2 - 10x + 25 = 17
In the problem with the white circle, x=100, in the problem with the blue circle, x might equal 165, but I'm not entirely certain. But I am certain about the first one.

Step-by-step explanation:
If you would like to find the sales necessary for the salesperson to earn at least 800 in one week, you can calculate this using the following steps:
s ... weekly sales
350 + 10% of sales >= 800
<span>350 + 10% of s >= 800
</span>350 + 10% * s >= 800
10/100 * s >= 800 - 350
1/10 * s >= 450 /*10
s >= 450 * 10
s >= 4500
The correct result would be: <span>weekly sales >= 4500.</span>
