x−y=0
Answers
Answer:
2. yes; the equation can be written as y = kx; k = 1
Step-by-step explanation:
x-y = 0
That means x and y have to be the same value.
If you multiply a number by 1, you get the same thing.
If you multiply x by one, you get y (the same value).

Mr. Samuuel Salesman is paid $125 a month. He also earns $50 for every vacuum he sells.
I need to find an equation, a table, and a graph
Answers
Answer:
earnings = $125 + ($50/vacuum)x
Step-by-step explanation:
This problem is best described by a linear equation whose slope is $50/vacuum and whose y-intercept is $125:
The equation represents the man's total earnings. The independent variable is x, the number of vacuums he sells.
Thus, earnings = $125 + ($50/vacuum)x. As before, the y-intercept is $125 and the slope of the line is ($50/vacuum).
Plot a black dot at (0, $125). Now move 2 units to the right from this dot and from there up by $100 to (2, $225). Plot this new point. Then draw a line through the two points you've plotted.
Table:
x earnings
---- --------------
0 $125
1 $125 + $50 = $175
2 $125 + $100 = $225
and so on.

For questions #9 - 11 "finding the slope" of a linear (straight) line, recall the "tools" that we can use:
1) Given a Graph: Slope or "m" = rise/run from one (x, y) point to a second (x, y) point on the line
2) Given any two (x, y) points on the line: Slope or "m" = y2 - y1 / x2 - x1
3) Given a "Table of Values": Choose any two (x, y) points in the table, then calculate the slope using the slope formula - Slope or "m" = y2 - y1 / x2 - x1

A TV has an original price of $499. Find the new price given a 10% increase.
Answers
Have a great day/night
Answer: $548.9
Step-by-step explanation:
To find the next price you have to find 10% of the original price then add it. You can find the increase by dividing 499 by 10 to get 10%.
499 divided by 10 = 49.9
Now add the increase to the original price for your answer!
499 + 49.9 = $548.9
Explain how to compare decimals. Use the numbers 6.75 and 6.732 to help you explain this process.
tysm I am struggling
Answers
Answer:
6.75>6.732
Step-by-step explanation:
We are given that
6.75 and 6.732
We have to compare two given decimal numbers.
First we convert like decimal number
In 6.75 there are two digits after decimal point.
In 6.732 , there are three digits after decimal point
Therefore, we put zero in 6.75 to convert like decimal number
Now, we get
6.750
Unit place of both decimal numbers are same and tenth place of both decimal number are same.
Now, hundredth place of 6.750 is 5 and hundredth place of 6.732 is 3
5 >3
Therefore, 6.750 is greater than 6.732
6.75>6.732

Which measure do you think would be the most helpful for her and why?
Answers
Answer:
Step-by-step explanation:
Firstly for the the mean you add all the numbers and divide by how many they are.73+88+85+88+99+134+129 and divide it by 7 .
Secondly for the median arrange the numbers numerical form and pick the middle number.
Mode is finding the most common number.
Range subtract the largest number from the smallest number.the best measure is mean because it shows you all you bought and helps in finding the perfect amount
Rewrite 1/5 barrel 1/2 hour as a unit rate
Answers
Hope this helps! ☺️
Unit rate of (1 /5 barrel) / (1/2hour) is equals to (2/5) barrels /hour.
What is unit rate?
"Unit rate is defined as the representation of the ratio of the two different units with value of the denominator equals to 1."
According to the question,
Given,
[tex]\frac{\frac{1}{5} barrel}{\frac{1}{2} hour}[/tex]
⇒ (1 / 2) hour = ( 1/ 5) barrel
⇒ 1 hour = ( 2 / 5) barrel
⇒( 2 / 5) barrel per 1 hour
Therefore,
Unit rate of given value is rewritten as
[tex]\frac{2}{5}[/tex] barrel / hour

The first two shipping companies provided their data from a sample of drivers in a table.
Company C showed its data in a dot plot.
Answer the questions to compare the mean number of deliveries for the three companies.
1. How many drivers did company C use in its sample?
2. What is the MAD for company C's data? Show your work.
3. Which company had the greatest mean number of deliveries?
4. Compare the means for companies A and B. By how many times the MAD do their means differ? Show your work.
Answers
Answer:
The means differ by 4 times the MAD.
Step-by-step explanation:
I may be missing something, but this is how I interpret it.
The mean number of deliveries for company A is 6, and the mean for company B is 14. Lastly, the mean absolute deviation (MAD) for both companies is 2.
[tex]14-6=8\\8\div2=4[/tex]
The means differ by 8, and that is 4 times the MAD, so the means differ by 4 times the MAD.
