Simplify 3/4(1/2×-12)+4/5

Wittaler [7]

Answer: $\frac{3}{8}x-\frac{41}{5}$ or $\frac{3}{8}x-8\ \frac{1}{5}$

Step-by-step explanation:

Given the following expression:

$\frac{3}{4}(\frac{1}{2}x-12)+\frac{4}{5}$

You can follow these steps in order to simplify it:

1. You need to apply Distributive property:

$=\frac{3}{8}x-9+\frac{4}{5}$

2. And now you must add the like terms. Then:

$=\frac{3}{8}x-\frac{41}{5}$

Therefore you get the following answer:

$\frac{3}{8}x-\frac{41}{5}$ or $\frac{3}{8}x-8\ \frac{1}{5}$

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:

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