Answer:

- 18y = 1

Step-by-step explanation:

Adding the 2 equations term by term on both sides gives

(- 5x + 5x) + (- 9y - 9y) = (3 - 2), that is

0 + (- 18y) = 1

- 18y = 1

Simplify (36/81) raised to the power -1/2

rosijanka [135]

Step-by-step explanation:

Hey, there!!

I hope you mean,

$\frac{ - 1}{2} \: means \: \sqrt{}$

and

$36 = {6}^{2} \: and \: 81 = {9}^{2}$

$so \: \: \sqrt{ \frac{ {6}^{2} }{ {9}^{2} } }$

$or \: ( { \frac{ {6}^{2} }{ {9}^{2} }) }^{ \frac{ - 1}{2} }$

so, the answer is 6/9 or, 2/3.

An employee earns $195 for 15 hours of work. Assuming he is paid by the hour, how much will the employee earn in 8 hours?

vampirchik [111]

Answer:

$104

Step-by-step explanation:

First, find the employee’s hourly rate. You can do this by dividing the total amount earned by the total hours worked. $\frac{195}{15}=13$
Now that you know that the employee’s hourly rate is $13 per hour, you can multiply the hourly rate by the number of hours. $13*8=104$

The slope of this trend line is m = (0-28) / (14-0) = -2. The y-intercept can be read directly from the graph: It is 28. Thus, the equation of this trend line is k = -2J + 28.
