3. Logan bus white, black, and grey tiles for his bathroom floor the number of black tiles he buys is 10 more then twice the number of Black tiles. He bus 100 great times if he buys 260 tiles in total, how many of each color did he buy (in equation from)

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this

well we know there are 4 clubs in 52 cards so it’s replaced so it should be 3/51
