Answer:

When x= 7/3, y = 2.

Step-by-step explanation:

When two variables are inversely related, it means that if one variable increases, the other one decreases. This relationship can be expressed as:

y = k/x, where "x" and "y" are variables and "k" the proportionality constant.

As the problem states, if y= 7 then x = 2/3. Now we can find the value of the constant "k"

7 = k/(2/3) ⇒ 7 x (2/3) = k ⇒ 14/3 = k.

So the equation for "x" and "y" ⇒ y = 14/3x

Finally you have to replace x = 7/3

⇒ y = 14/[3 x (7/3)] ⇒ y = 2.

Summarizing, when x = 7/3, y = 2.

Y=k/x
7=k/(2/3)
7=k(3/2)
times both sides by 2/3
14/3=k

y=(14/3)/x
y=(14/3)/(7/3)
y=(14/3)(3/7)
y=2

DanielleElmas [232]

It should be noted that the hourly delivery rate is calculated by dividing the income made by the number of hours worked.

<h3>How to calculate the hourly delivery rate</h3>

Your information is incomplete. Therefore, an overview of the information will be given.

In order to get an hourly rate, it's important to divide the income that the person gets by the number of hours that the person worked.

In this case, let's say that the income is $20000 and the number of hours that was worked monthly was 240 hours, the hourly rate will be:

= $2000/240

= $8.33 per hour

How do I make a linear function, what is a linear function?
mixer [17]

Answer:

I have uploaded a picture so you could understand it a little more.

A linear function is when there is a table that gives numbers that represent a function, as shown in the picture.

In the Image, there is a table with a x and y column. And in both columns, there are numbers.

This is what the table looks like in the picture:

<u>  x   y   </u>

0    4                       The key is y = 2x + 4

1     6 <------      lets grab the number 1 in the x column and lets

2    8       multiply it by two.  Now add four to it, and we will

3    10                  have the number 6 in the y column.

4    12
