Answer:
Step-by-step explanation:
Use the formula for the volume of a cylinder:
Volume= B times height
Being "B" the area of the cylinder's base (a circle of radius 4.5 ft.
Therefore the area of the base is:
So the volume of the cylinder is:
-7(x + 9) = 9(x - 5) - 14x Solve for x. SHOW WORK.

<u>Answer:</u>
x=-9
<u>Step-by-step explanation:</u>
STEP 1: Since x is on the right side of the equation, switch the sides so it is on the left side of the equation.
<em />
STEP 2: Simplify 9(x−5)−14x.
STEP 3: Simplify −7(x+9).
STEP 4: Move all terms containing x to the left side of the equation.
STEP 5: Move all terms not containing x to the right side of the equation.
STEP 6: Divide each term by 2 and simplify.

Answer: Choice C
========================================================
Explanation:
The vertical asymptotes are the red dashed lines. They are x = -4 and x = 0. Think of them as electric fences that the graph cannot touch or cross. The curve can only get closer and closer.
The vertical asymptote is due to a division by zero error.
When x = 0, the denominator x(x+4) turns into 0 since
x(x+4) = 0(0+4) = 0*4 = 0
Similarly, when x = -4, the denominator is also zero
x(x+4) = -4(-4+4) = -4*0 = 0
So if x = -4 or x = 0, then we have a division by zero error and that's what produces the vertical asymptotes at those locations shown on the graph.
This is why the answer is choice C.
