-2r+8

The first step is to combine like terms. These would be 4r, -7r, and r since they have the same variable. This gives you -2r. Since there are no other like terms to combine, you end up with -2r+8

A company ships coffee mugs using boxes in the shape of cubes. The function g(x) = gives the side length, in inches, for a cube
Gekata [30.6K]

Answer:

The graph is attached below.

Step-by-step explanation:

The volume of the box containing the coffee mugs is,

V=x^{3}

Then the function representing the side length, in inches, for the box is:

g(x)=x

Now, it is provided that the company decides to double the volume of the box.

That is, the new volume will be:

V_{n}=2x^{3}

Then the side length, in inches, for the box will be:

g_{n}(x)=\sqrt[3]{2x^{3}} =\sqrt[3]{2}x

Then the graph representing the function, formed using the following points is:

x\ \ \ \ \ \ \ \ \ g_{n}(x)\\\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\\0\ \ \ \ \ \ \ \ \ \ \ 0\\1\ \ \ \ \ \ \ \ \ \ \ 2^{1/3}
