Expressions are said to be equivalent if they hold the same value.

$6x - \frac{2}{5}$ and $\frac{6}{5x} -\frac{2}{5}$ are not equivalent.

Given that:

$6x - \frac{2}{5}$

Take LCM

$6x - \frac{2}{5} = \frac{6 \times 5x -2}{5}$

By comparison:

$\frac{6 \times 5x -2}{5}$ is not equal to $\frac{6}{5x} -\frac{2}{5}$

i.e.

$\frac{6 \times 5x -2}{5} \ne \frac{6}{5x} -\frac{2}{5}$

Hence,

$6x - \frac{2}{5}$ and $\frac{6}{5x} -\frac{2}{5}$ are not equivalent.

What is the domain of the function graphed ?

ankoles [38]

Remember that the domain is all possible x values.

Here, the highest x value is 2 and the lowest is -4, which makes A and D incorrect.
x can also be anything between 2 and -4, so B is also incorrect.

That leaves C our answer.

Your local coffee shop has announced new hours of operation. Previously: 7 am – 4 pm Monday thru Friday and 7am to Noon Saturday

LekaFEV [45]

Part (a)
=======
See the attached figure which represents the problem.
So, we can note that there are 3 hours increase from Monday thru Friday

and 4 hours increase in both of Saturday and Sunday

So, the increase in total hours opened = 3*5 + 4*2 = 23 hours

======================================================

Part (b):

=====

weekly original payroll $ 385

Total working of old hours = 9 * 5 + 5 * 2 = 55 hours
so, the hourly payroll = 385/55 = $ 7
Assume the hourly wage will stay the same

Total working of new hours = 55 + 23 = 78 hours

So, the total weekly pay under the new hours = 78 * 7 = $ 546

=====================================================
Part (c):
========
The total pay for old hours = $ 385
The total pay for new hours = $ 546
The increase in the total pay = 546 - 385 = $ 161

The percentage increase in total pay = $\frac{161}{385} *100 = 41.8%$
