Name Kuta Software - Infinite Algebra 2 Systems of Two Equations Solve each system by graphing. Date 1) y=-3x + 4 y= 3x - 2 2) y

Viktor [21]

Lets make the graph of our systems of equations:

The blue line correspond to the equation x-y=3 and the red one correspond to 7x-y=-3. The lines intersect at point (-1,-4), then, the solution of the system is (-1,-4).

If the graphs of the linear equations in a system are the same line, what does that mean about the possible solution or solution

Mademuasel [1]

Answer:

If we have a system of linear equations:

y = a*x + b

y = c*x + d

And the graphs of the equations are the same line, this means that both lines have the same equation, then:

a = c and b = d.

Then we have only one equation (but repeated) and two variables, then we have infinite solutions for our system.

Another way to see this is:

When we have a system of linear equations, the solution is the point where the lines intersect.

But if both lines are the same line, then the lines intersect in infinite points, then we have infinite solutions.

Asap<br> Select the correct answer.<br> Which function has a restricted domain?

german

Step-by-step explanation:

Check second one

$\\ \rm\Rrightarrow k(x)=(-x+3)^{\frac{1}{2}}$

1/2 means square root

$\\ \rm\Rrightarrow \sqrt{(-x+3)}$

$\\ \rm\Rrightarrow -x+3>0$

$\\ \rm\Rrightarrow -x>-3$

$\\ \rm\Rrightarrow x$

Hence.

Domain is restricted

Option B is correct
