Graph the funxtion y=|x+2|-3

zhenek [66]

First you need to pick a number for y. Lets say you pick 0
Then you need to +3 to each side
Then you can say 3=x+2 or -3=x+2.
To find x you need to subtract 2.
You answer would be (1,3) and (-5.-3)

Select the correct answer.

Katen [24]

Answer:

A. v= $3,995.72 - $1,838.03

Step-by-step explanation:

Given:

fixed expenses: $1,838.03

total expenses: $3,995.72

We need to find the amount of Variable expense (v).

Now We know that;

Variable expense (v) can be calculated by Subtracting Fixed expense form Total expense.

framing in equation form we get;

Variable expense (v) = total expenses - fixed expenses.

Variable expense (v) = $3,995.72 - $1,838.03 = $2,157.69

Hence The equation represents Jessie's variable expense (v) = $3,995.72 - $1,838.03

Raymond built a “rocket" made from a cylinder and a cone. He filled the rocket

lianna [129]

Answer:

Rocket can hold maximum 4.5 gallons of water.

Step-by-step explanation:

Volume of the rocket = Volume of the cone on the top + Volume of the cylinder at the bottom

Volume of the cone = $\frac{1}{3}\pi r^{2}h$

Here r = radius of the circular base

h = height of the cone

Volume = $\frac{1}{3}\pi (4)^{2}(14)$

= $\frac{224\pi }{3}$ cubic inch

Volume of the cylinder = $\pi r^{2}h$

Here r = radius of the base

h = height of the cylinder

Volume = $\pi (4)^{2}(16)$

= 256π cubic inches

Volume of the rocket = $\frac{224\pi }{3}+256\pi$

= $\frac{992\pi }{3}$

= 1038.82 cubic inches

Since 231 cubic inches volume of a rocket can hold water = 1 gallon

Therefore, 1038.82 cubic inches space can hold water

= $\frac{1038.82}{231}$

= 4.497

≈ 4.5 gallons

Rocket can hold 4.5 gallons of water.
