Fill in the Blanks

How many solutions exist for the graphed system?

Type your numerical answer into the box.

Multiple Choice

Which system of equations is displayed in the graph?

• $$y=\left(x+1\right)^2-3$$

  $$y=-\ \sqrt[]{x-1}-1$$

• $$y=\left|x+1\right|-3$$

  $$y=-\ \sqrt[]{x+1}-1$$

• $$y=\left|x-1\right|-3$$

  $$y=-\ \sqrt[]{x+1}-1$$

• $$y=-\left(x-1\right)^2-3$$ $$y=\sqrt[]{x+1}-1$$

Fill in the Blanks

What is the solution to the system of equations shown?

Type your answer as an ordered pair. Example: (5,-1)

Multiple Choice

Which system of inequalities matches the given graph?

• $$y>-x+3$$

  $$y\le\frac{2}{3}x-1$$

• $$y\le-x-3$$

  $$y>\frac{2}{3}x+1$$

• $$y<-x+3$$

  $$y\le\frac{2}{3}x-1$$

• $$y\le-x+3$$

  $$y>\frac{2}{3}x-1$$

Multiple Select

Select ANY coordinates that ARE solutions to the graph of the system of inequalities.

• (0, -1)

• (5, 0)

• (-5, 0)

• (-1, 2)

Multiple Choice

The Chess Club is selling brownies and lemon bars to raise money to travel out of state. They only have enough baking materials for no more than 200 brownies and lemon bars total, however, they need to make at least 630 dollars. If they sell each brownie for $4 and each lemon bar for $2.50, which system matches this scenario?

• $$b+l\le200$$

  $$4b+2.5l\ge630$$

• $$b+l>200$$

  $$4b+2.5l>630$$

• $$b+l\ge200$$

  $$4b+2.5l\le630$$

• $$b+l\le200$$

  $$4b+2.5l\le630$$

Multiple Choice

Which equation could pair with $$2y-x=7$$ to create a system with no solution?

• $$y=-\frac{1}{2}x+4$$

• $$y=\frac{1}{2}x+3$$

• $$y=2x-3$$

• $$y=\frac{2}{7}x+1$$

Solve the following system:

$−x+4y=25$

$-2x-2y=-10$

Write your answer as an ordered pair: (x,y).

If no solution exists, write "ns".

If there are infinitely many, write "ims".

Solve the following system:

$-3x+2y=1$

$6y=9x+3$

Write your answer as an ordered pair: (x,y).

If no solution exists, write "ns".

If there are infinitely many, write "ims".
