Yvonne is constructing a line perpendicular to and passing through point A on using only a compass and a straightedge. She has drawn arcs with a compass of set width centered at point A intersecting in two places. Yvonne labeled the points of intersection B and C. Which of the following sentences describes her next step in the construction? A. Place the compass needle on point B and set the width of the compass beyond point A. B. Place the compass needle on point A and set the width to half way between points B and A. C. Place the compass needle on point B and set the width to point A. D. Place the compass needle on point A and set the width beyond point B.

46.2+112.3

step-by-step explanation:

i believe that the answer is

b. y-1=-2(x-4)

hope this !

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
