Help me plz i need helppp

1) The system is <u>consistent and independent</u>.

2) The system is <u>inconsistent</u>.

3) The system is <u>inconsistent</u>.

<u>Step-by-step explanation</u>:

The system of equation is said to be

inconsistent - it has no solution

consistent - it has at least one solution.

independent - it has exactly one solution

dependent - it has more than one solution.

1)

2x - y = 3

<u>2x + y = 1</u>

<u>4x      =  4</u>

∴ The value of x=1 and substitute x=1 in any of the above equations.

y = -2(1) + 1 = -1

The system of equation has one solution (x,y) = (1,-1).

The system is <u>consistent and independent</u>.

2)

2x - y = 3

-4x + 2y = -6

Mulitply the 1st equation with 2 on both sides,

4x - 2y = 6

<u>-4x + 2y = -6</u>

<u>   0               </u>

The system of equation has no solution.

The system is <u>inconsistent</u>.

3)

2x - y = 3 , multiply by 2 on both sides.

we get, 4x - 2y = 6

            <u>-4x +2y = 6</u>

             <u>   0            </u>

The system of equation has no solution.

The system is <u>inconsistent</u>.

Q 1 Graph the function<br>Y = |X+2| -3
zimovet [89]
First of all we know the Absolute Value Function that is:

\left | x \right |= \left \{ {{x \ \ \ \ x \geq 0} \atop {-x \ \ \ \ x\ \textless \ 0}} \right.

This is called the Parent Function of the Absolute Value Function.

From the equation:

y=\left | x+2 \right |-3

The term:

\left | x+2 \right |

means that the the Parent Function is shifted two units to the left.

On the other hand, the term:

-3

means that the function \left | x+2 \right | is shifted three units <span>downward. </span>So the result is the graph shown below

Conclusion: <em>The graph is the second one.</em>
