What compound inequality describes this graph?

The answer to your question is   0 < x ≤ 3

Step-by-step explanation:

To write this inequality we must consider

- The value of the borders, for this inequality the borders are 0 and 3.

-The kind of border   - if it is an open point, we will use the symbol  <

                                  - if it is a close c point, we will use the symbol ≤

-The inequality for this problem will be

                              0 < x ≤ 3

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
