C, i dont know dont use my answer unless you know
Answer:
Step-by-step explanation:
In order to find the center and the radius of this circle, you have to complete the square on it. And only for the x-terms, because the y term is squared and there is no other y term. We'll get to that in a second.
Take half the linear x-term, square it and add it to both sides. Our linear term is 10. Half of 10 is 5, and 5 squared is 25. We add 25 to both sides:
The reason we do this is to create a perfect square binomial inside that set of parenthesis. Simplifying the right side as well gives us:
This tells us that the center is (-5, 0). Remember when I said we would get back to the y terms? Because there was only a y-squared and no other y terms, that is the same as writing the equation as
The radius is the square root of the constant. So the radius is 6.
D is the graph you want.
Answer:
x = 13
Step-by-step explanation:
1765
x = 100 (9) + (7) 50 + (19) 20 + (7) 10 - 1765
x = 900 + 350 + 380 + 70 - 1765
x = 1700 - 1765
x = -65
65/5 = 13
x = 13
