(20*16 ft^2)(144 in^2/ft^2)(tiles/(10*10 in^2)
320ft^2(144in^2/ft^2)(tiles/100in^2)=460.8 tiles
However tiles are quantized integer units so 461 tiles will be needed to tile the kitchen.
0.270 repeated. I used long division and a calculator. hoped this helped.
Vertex form is y=a(x-h)^2+k
you need to find a perfect square
y=x^2+24x+<u> </u>+29 -<u>
</u>y=x^2+24x+144+29-144
y=(x+12)^2 +29-144
y=(x+12)^2-115
Is that what your looking for or no
So the easiest way to do this is to convert this standard form equation into slope-intercept form, which is y = mx+b (m = slope, b = y-intercept). The slope indicates whether the line is going upwards and downwards and at what rate, and the y-intercept is where the line crosses the y-axis.
Firstly, subtract both sides by 6x:
Next, divide both sides by 8 and your slope-intercept form will be:
So with this equation, since the slope is negative, the line is going downwards. You will graph this line so that when x increases by 3, y decreases by 2 and so that the line passes (0,-4). Here are some of the points on this line to help you:
(0,-4), (3, -6), (6,-8), etc.
