The price, x, of a hat was first reduced by 20%, and then the new price was further reduced by 30%. What expression identifies the price of the hat after the two reductions?

The price, x, of a hat was first reduced by 20%, and then the new price was further reduced by 30%. What expression identifies the price of the hat after the two reductions?

A) x - 30
B) x - 0.5x
C) x + 0.5x
D) x - 0.5x + 0.06x

The answer is D. I just took the quiz

x - 0.5x + 0.06x

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.
