This question is based upon the (incorrect) idea that all 3 of these bottles are uniformly-shaped cylinders.  But I'd suggest you accept that convention.

The volume of a right circular cylinder is V = (base)(height), where the (base) is the base area:  A=pi * r^2, where pi is taken to be 3.14.

Last case:  the radius is 6 cm and the height is 32 cm.  The area of the base is then 3.14 * 6^2 cm^2 (simplify this), and the height is 32 cm.  Multiply these together to obtain the volume of the bottle.  Be certain to include the unit of measurement, cm^3.

Which of the following equations represents the line with a slope of 2/3 and a y-intercept of 9?
Olegator [25]

y = mx + b where m = slope and b = y intercept

In this case, it's given a slope of 2/3 and a y-intercept of 9

So equation y = 2/3 x + 9

Answer

y = 2/3 x + 9

Solving systems using substitution
netineya [11]

Answer:

2) x=-4 y=4 4) x=0 y=-4

Step-by-step explanation:

<em>2)</em> Step: Substitute x+8 for y in y=−4x−12:

y=−4x−12

x+8=−4x−12

x+8+4x=−4x−12+4x  (Add 4x to both sides)

5x+8=−12

5x+8+−8=−12+−8 (Add -8 to both sides)

5x=−20

5x /5 = −20 /5 (Divide both sides by 5)

x=−4

Step: Substitute −4 for x in y=x+8:

y=x+8

y=−4+8

y=4 (Simplify both sides of the equation)

Answer:

x=−4 and y=4

<em>4) </em>Step: Substitute 3x−4 for y in y=x−4:

y=x−4

3x−4=x−4

3x−4+−x=x−4+−x  (Add -x to both sides)

2x−4=−4

2x−4+4=−4+4  (Add 4 to both sides)

2x=0

2x/2  =  0 /2 (Divide both sides by 2)

x=0

Step: Substitute 0 for x in y=3x−4:

y=3x−4

y=(3)(0)−4

y=−4 (Simplify both sides of the equation)

Answer:

x=0 and y=−4
