Answer:

Check the figure attached.

Step-by-step explanation:

We have

Expression in Rectangle 1= 4x+3y

Expression in Rectangle 2 = 2x-y

Their sum will be in circle 1

adding:

$4x+3y+2x-y \\=4x+2x+3y-y\\=6x+2y$

Now using the expression in Rectangle 3 and circle 3, we can find expression Of rectangle 4. Let it be Exp

$x+4y+Exp=4x+5y\\Exp=4x+5y-(x+4y)\\Exp=4x+5y-x-4y\\Exp=4x-x+5y-4y\\Exp=3x+y\\$

Now using Expression in rectangle 2 and 4 to find result for circle 3

$2x-y+3x+y\\=2x+3x-y+y\\=5x$

Now adding terms in the figure

Graphing inequalities

dem82 [27]

There are three steps:
1.)Rearrange the equation so "y" is on the left and everything else on the right.

2.)Plot the "y=" line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)

3.)Shade above the line for a "greater than" (y> or y≥) or below the line for a "less than" (y< or y≤).

How many units of a 10% solution are needed to prepare 500 units of a 2% solution?

Akimi4 [234]

First find how many units of solution there is:

500* 2% = 500(.02) = 10 units

You need 10 units of solution in 'x' units of a 10% solution.

x*10% = 0.1x = 10 units -----> x = 10/0.1 = 100

100 units are needed
