B= r+k 3 110 f for r, №18011313, 16.12.2020 01:03.

Step-by-step explanation:1. Write the expression.

B= r+k 3 110 f for r, №18011313, 16.12.2020 01:03

2. Divide by f on both sides.

B= r+k 3 110 f for r, №18011313, 16.12.2020 01:03

3. Multiply both sides by 3.

B= r+k 3 110 f for r, №18011313, 16.12.2020 01:03

3. Substract k from both sides.

B= r+k 3 110 f for r, №18011313, 16.12.2020 01:03

4. Reorganize.

B= r+k 3 110 f for r, №18011313, 16.12.2020 01:03.

r=\frac{3B}{f}-k.

Step-by-step explanation:1. Write the expression.

B=(\frac{r+k}{3} )f

2. Divide by f on both sides.

\frac{B}{f} =[(\frac{r+k}{3} )f]/f\\ \\\frac{B}{f} =\frac{r+k}{3}

3. Multiply both sides by 3.

\frac{3B}{f} =r+k

3. Substract k from both sides.

\frac{3B}{f}-k =r+k-k\\ \\\frac{3B}{f}-k =r

4. Reorganize.

r=\frac{3B}{f}-k.

The system of inequalities represented by the graph is:

y ≥ 3x + 6 (represented by the line passing through the points (0, 6) and (-2, 0) with shaded region above the line)

y < -x - 6 (represented by the line passing through the points (0, -6) and (-6, 0) with shaded region below the line)

So, the correct answer is:

y ≥ 3x + 6 (Option D)
