Looking at this problem in terms of geometry makes it easier than trying to think of it algebraically.

If you want the largest possible x+y, it's equivalent to finding a rectangle with width x and length y that has the largest perimeter.

If you want the smallest possible x+y, it's equivalent to finding the rectangle with the smallest perimeter.

However, the area x*y must be constant and = 100.

We know that a square has the smallest perimeter to area ratio. This means that the smallest perimeter rectangle with area 100 is a square with side length 10. For this square, x+y = 20.

We also know that the further the rectangle stretches, the larger its perimeter to area ratio becomes. This means that a rectangle with side lengths 100 and 1 with an area of 100 has the largest perimeter. For this rectangle, x+y = 101.

So, the difference between the max and min values of x+y = 101 - 20 = 81.

Put the following equation of a line into slope-intercept form, simplifying all fractions.
Inessa [10]

Answer:

y=\frac{3}{5} x-3

Step-by-step explanation:

<u>Slope-intercept form:</u> y = mx+ b

m = slope

b = y-intercept

<u>Rearrange the equation:</u>

-20y=-12x+60

<u>Divide each side by -20:</u>

\frac{-20y}{-20} =\frac{-12x}{-20} +\frac{60}{-20}

y=\frac{3}{5} x-3

y=\frac{3}{5} x-3 is your simplified, slope-intercept form equation.

Abigail is putting tiles on a table top. She needs 48 tiles for each of 8 rows. Each row will have 6 white tiles.
almond37 [142]
I think its like this 
each row has 6 white tiles
8 rows = 48 tiles 
48 - 6 = 42
42 x 8 = 336
so 8 rows = 6 white tiles and 42 purple tiles to make 48 tiles so she will need 336 more tiles to make each 8 rows have 48 tiles

hope this helps : )

Which of the following order pairs is a solution of x+1/2y=1?<br><br> (-2,6)<br> (2,-6)<br> (-2,-6)
julsineya [31]
Y/2=1-x

y=2-2x

y(-2)=2-2(-2)=2+4=6, (-2,6)

So (-2, 6) is an ordered pair from x+y/2=1
