After you simplify the answer comes to 0, which leaves your correct
choice to be D. 0

Consider a circle whose equation is x + y - 2x - 8=0. Which statements are true? Select three options

Mandarinka [93]

Answer:

The standard form of the equation is

${(x - 1)}^{2} + {(y - 0)}^{2} = {3}^{2}$

Step-by-step explanation:

The given circle has equation:

${x}^{2} + {y}^{2} - 2x - 8 = 0$

We regroup similar terms to obtain:

${x}^{2} -2x + {y}^{2} = 8$

We now complete the square to obtain:

${x}^{2} -2x + {( - 1)}^{2} + {y}^{2} = 8 + {( - 1)}^{2}$

${(x - 1)}^{2} + {(y - 0)}^{2} = 9$

${(x - 1)}^{2} + {(y - 0)}^{2} = {3}^{2}$

This is now of the form:

${(x - h)}^{2} + {(y - k)}^{2} = {r}^{2}$

which is referred to as the standard form equation of the circle:
