Segment AB is on the line y − 3 = 2(x + 2), and segment CD is on the line y − 3 = negative one half(x + 2). Which statement proves the relationship of segments AB and CD?

A. They are parallel because they have the same slope of 2.
B. They are parallel because they have the same slope of negative one half.
C. They are perpendicular because they have slopes that are opposite reciprocals of 2 and negative one half.
D. They are perpendicular because they have slopes that are opposite reciprocals of −2 and one half.

answer:

i think its c , might be wrong!

Step-by-step explanation:

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1

step-by-step explanation:

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.
