It is 9. You have to add 33y, then divide by 11 and you get x = 3y + 9

Subtract the function f(x) = 6x -- 5 from the function g(x) = -2% +9.

densk [106]

We want h(x) = g(x) - f(x).

h(x) = -2x + 9 -(6x - 5)

h(x) = -2x + 9 -6x + 5

h(x) = -8x + 14

What is container B that is full after the pumping is complete ?

Step-by-step explanation

The volume of a cylinder is calculated as follows:

$V=\pi r^2h$

where r is the radius and h is the height of the cylinder.

In the case of cylinder A, its radius is r = 5 ft (= 10/2) and its height is h = 14 ft. Then, its volume is:

$\begin{gathered} V_A=\pi\cdot5^2\cdot14 \\ V_A=350\pi\text{ ft}^3 \end{gathered}$

In the case of cylinder B, its radius is r = 8 ft (= 16/2) and its height is h = 8 ft. Then, its volume is:

$\begin{gathered} V_B=\pi\cdot8^2\cdot8 \\ V_B=512\pi\text{ ft}^3 \end{gathered}$

After the pumping is completed all the liquid in cylinder A, which was full, is placed in cylinder B. If the volume of cylinder B represents 100%, then we need to find what percent, x, represents the volume of cylinder A. We can do this with the help of the next proportion:
