You have to move 14 to the right hand side and subtract it from 8. You will get 5|x+7|=-6 which is false so the answer is no solution

Answer:

A. 1,485 cubic cm. B. 27

Step-by-step explanation:

The new prism is dilated by a factor of 3, that means it's made bigger, 3 times bigger on each side.

The dimensions of the new prism are then 12 cm by 7.5 cm by 16.5 cm.

Its volume is then of 12 x 7.5 x 16.5 = 1,485 cubic cm

To answer the second question...

Let's calculate the volume of the original prism:

The original prism's volume was 4 x 2.5 x 5.5 = 55 cubic cm

The new volume is then 1485 / 55 = 27 times bigger than the original.

Which is normal, since we increased each side (dimension) by a factor of 3, so 3x3x3 = 27.

What is the constant rate of change from the graph?

Harlamova29_29 [7]

Answer:

$5$

Step-by-step explanation:

When looking for constant rate, you have to see what is the repeating rate or coordinate in order to solve constant rate.

Let us take two coordinate points,

( 1 , 5 )
( 3 , 15 )

If we were to look for constant rate, we have to see the similarity (in this case the multiplication of the two numbers) between the two points.

What can they be?

They both have x multiplying by 5 to get y!

1 * 5 = 5

3 * 5 = 15

The same goes with all other points on the graph, leaving you with five as the constant rate.
