There are two ways to confirm this is the answer. The first is to note that (3,-2) is on the boundary, so it is part of the solution set. This only works if the boundary line is a solid line (as opposed to a dashed or dotted line).

The second way is to plug (x,y) = (3,-2) into the given inequality to find that

$y \le -x+1\\\\-2 \le -3+1\\\\-2 \le -2$

which is a true statement. So this confirms that (3,-2) is in the solution set of the inequality.

Carlos uses a 3-D printer that melts plastic to produce custom action figures. The growth shows the amount of plastic it melts O

IceJOKER [234]

Answer and Step-by-step explanation:

It be more than 2 ounces and less than 1.5 ounces

The amount of plastic that is melted in 5.7 minutes is 1.71

To find this, you would use the point on the graph. Divide both of those numbers by 4.

(4, 1.2)

4/4 = 1.

1.2/4 = 0.3.

So, for every minute, 0.3 of an ounce of plastic is melted.

We then multiply 0.3 by 5.7 to get 1.71.
