the way to answer this is you have find out coordinates of BC and since i cant see the graph im no help. y will equal whatever you can get from there .

**Answer:**

4/3π(0.973r³)

**Step-by-step explanation:**

Volume of a sphere = 4/3πr³

Given the radius of dodge ball rd = r

radius of tennis ball rt = 0.3r

Taking their difference

Volume difference = 4/3πrd³ - 4/3πrt³

Volume difference = 4/3π(r)³ - 4/3π(0.3r)³

Volume difference = 4/3π(r³ - 0.027r³)

Volume difference = 4/3π(0.973r³)

**Hence the differmce in volume is 4/3π(0.973r³)**

Multiply both sides by 12, which becomes (12*6)/9 = w as the the 12 cancels out on the right side. This becomes 72/9 = w and since 9 goes into 72 8 times, 8 = w

**Answer:**

B) -1

**Step-by-step explanation:**

3+2(-1)=2(-8-6(-1))-5(-1)

3-2=2(-8+6)+5

1=2(-2)+5

1=-4+5

1=1

The equation for the line to graph would be y = 47.5x + 50
