To convert a quadratic from y = ax2 + bx + c form to vertex form, y = a(x - h)2+ k, you use the process of completing the square.

(-5,-3) since plug in a=b-2 into the first equation and then solver for b. You get -3.-3-2=-5 which is a

Tiles are ordered in "squares" that contain about 171 tiles in each square.The Lees need 21 squares for the entire roof. How man

If a square contains 171 tiles you will need multiply 21 by 171 (171x21) which should give you the amount for the entire roof.

Hope this helps! :)

Kitchen is shaped like a rectangle with dimensions of 11 1/2‘ x 9 1/2‘. The floor of the room is made of square tiles with a sid

Masja [62]

-- The area of the kitchen floor is (11.5 ft) x (9.5 ft) = 109.25 square ft.

-- The area of each tile is (0.5) x (0.5) = 0.25 square ft.

-- If the tiles are carefully placed, with no overlap and no big sloppy spaces
between them, the number of tiles required to cover the floor is

(109.25 ft²) / (0.25 ft²/tile) = 437 tiles .

hyperbola with center at (0,0) with x intercepts at (4,0) and (-4,0) with b= 1 , opening horizontally equation

Tanya [424]

Check the picture below.

now, if the x-intercepts are at ±4 whilst the center is at the origin, that means the vertices are the ones hitting the x-axis, like in the picture, so just plug in the values for a, b, h and k.
