Step-by-step explanation:
1. 3x + 2y - 2x + y + 12 is equivalent to x + 3y + 12
2. 4y + 3y + 3x - 6y - 10 - 2 is equivalent to 3x + y - 12
3. x + 3y + 2x - 3x + 7 + 5 is equivalent to 3y + 12
4. I do not know unfortunately
Answer:
See attached image
Step-by-step explanation:
To solve this, first simplify the compound expressions - the ones with multiple x, y terms and see which of the other expressions matches the simplified expression
I will tell you how to solve one of the more complex expressions; the technique is the same for the rest
Let's take the very last expression
4y + 3y + 3x - 6y -10 - 2
To simplify,
group like terms:
=(4y + 3y - 6y) + 3x +(-10 -2)
= y + 3x - 12
Rewriting with x before y gives
3x + y - 12
and there is a matching 3x + y - 12
4y + 3y + 3x - 6y -10 - 2 ⇔ 3x + y - 12
The solution is in the attached image

What is the meaning of the word lucrative as it is used in the following sentence?
"Looks like my Internet business is pretty lucrative, wouldn't you say?"
Perfect
To strongly disagree
Your salary is extremely high because of all the money you make
Profitable, you make money from it
Answers
Answer:
Profitable, you make money from it.
Step-by-step explanation:
In this sentence, there is no sort of disagreement or talk about salary, and the word perfect does not fit the sentence structure.
Profitable, you make money from it. is the correct answer because the speaker is saying, "Looks like my internet business is (pretty lucrative)..."
-lucrative means profitable. Therefore the speaker is talking about how his business is successful, and doing well at the moment.
For five days, Diego recorded the lengths, in minutes, of his walk to school. The mean for his data is 11 minutes. Determine which data set below is Diego’s, and prove that your choice is correct.
Answers
Data Set A: 9, 11, 13, 10, 12
Data Set B: 8, 10, 12, 14, 16
Data Set C: 10, 10, 10, 10, 10
Data Set D: 11, 11, 11, 11, 11
To find the mean, we sum up all the values in each data set and divide by the number of values:
Data Set A: (9 + 11 + 13 + 10 + 12) / 5 = 11 minutes
Data Set B: (8 + 10 + 12 + 14 + 16) / 5 = 12 minutes
Data Set C: (10 + 10 + 10 + 10 + 10) / 5 = 10 minutes
Data Set D: (11 + 11 + 11 + 11 + 11) / 5 = 11 minutes
Comparing the mean of each data set to 11 minutes, we can see that only Data Set A and Data Set D have a mean of 11 minutes. However, to prove that our choice is correct, we need to analyze the individual values in the data set.
In Data Set A, we can observe that the values are relatively close to 11 minutes, with some values slightly above and below. This variation suggests a realistic scenario where Diego's walk to school might take slightly different amounts of time each day.
In Data Set D, all the values are exactly 11 minutes. While it is not impossible for Diego's walk to consistently take exactly 11 minutes each day, it seems less likely than having some variation in the durations.
Based on these observations, we can conclude that the most plausible data set for Diego is:
Data Set A: 9, 11, 13, 10, 12
This data set has a mean of 11 minutes and exhibits a realistic variation in walk durations, making it the most likely choice for Diego's recorded lengths.
A project will take a total of 720 person-days to complete. If the project must be completed in 30 days, how many people must be employed? PLEASE HURRY
Answers
Answer:
192 hours per day / 8 hours per person per day = 24 people
Step-by-step explanation:
Assuming each person works for 8 hours a day, the total number of hours needed to complete the project is:
720 person-days x 8 hours = 5,760 hours
To complete the project in 30 days, the total number of hours needed per day is:
5,760 hours / 30 days = 192 hours per day
Mateo’s old bedroom was a square with integer dimensions. His new bedroom is 3 feet wider and 2 feet longer. The increase in area is 46 ft^2. What were the dimensions of Mateo’s old bedroom?
Answers
Let x be the length of Mateo's old bedroom, then its width is also x since it is a square.
The new bedroom's length is x + 2 and its width is x + 3. The area of the new bedroom is (x + 2)(x + 3).
We know that the increase in area is 46 ft^2, so we can write an equation:
(x + 2)(x + 3) - x^2 = 46
Expanding the left side of the equation and simplifying, we get:
x^2 + 5x - 40 = 0
Factoring, we get:
(x + 8)(x - 5) = 0
Since the dimensions of the bedroom must be positive, we can discard the negative solution x = -8. Therefore, the length of Mateo's old bedroom is x = 5 feet, and its dimensions are 5 ft by 5 ft.

Step-by-step explanation
#1 apply the exponet rule a -¹ = 1/a
(2/3) ^-1 =1/2/3 Apply the fraction rule then you get 3/2
#2 (4/5)^-2 = 1/(4/5)^2 ,
(4/5)^2= 16/25
then you get your answer 25/16
#3 ((x/x^2)^3)^2 =(x/x^2) 3times 2
multiply the numbers 3 times 2 = 6
= (x/x^2)^6
(x/x^2)^6= x^6/(x^2)^6
simplify (x^2)^6: x^12
x^6/x^12(fraction)
x^6/x^12= 1/x^12-6
subtract the numbers 12-6=6
=1/x^6

After 1 year, $50,000 deposited in a savings account with simple interest had earned $2,500 in interest. What was the interest rate?
pls explain how as well if you don't mind
Answers
Answer:
5%
Step-by-step explanation:
The formula for calculating simple interest is:
Interest = Principal × Rate × Time
Where:
Interest is the amount of money earned as interest
Principal is the initial amount of money deposited
Rate is the interest rate (expressed as a decimal)
Time is the duration for which the money is invested or the time period over which interest is calculated
In this scenario, the principal amount is $50,000, and the interest earned is $2,500. The time period is given as 1 year.
We can rearrange the formula to solve for the rate:
Rate = Interest / (Principal × Time)
Plugging in the given values:
Rate = $2,500 / ($50,000 × 1)
The calculation simplifies to:
Rate = $2,500 / $50,000
Dividing $2,500 by $50,000 gives us the decimal value of the interest rate:
Rate = 0.05
To express the interest rate as a percentage, we multiply the decimal value by 100:
Rate = 0.05 × 100
Rate = 5%
Therefore, the interest rate for the savings account is 5%.
Answer:
Interest Rate = 5%
Step-by-step explanation:
Principal = $50, 000
Rate = ?
Time = 1 yr
S.I = PRT/100
2,500/1 = 50,000 × R × 1/100
50,000R = 2,500 × 100
50,000R = 250,000
50,000R/50,000 = 250,000/50,000
R = 5 %

which statement correctly compares the function shown on this graph with the function y=6x-1
Answers
Answer:
D.
Step-by-step explanation:
The function shown on the graph is y = 5x - 6 and it is being comapred to y = 6x - 1. The function shown on the graph has a smaller rate of change because 5x < 6x. The starting point of the function shown on the graph is also lower since - 6 < - 1.
The statement correctly compares the function shown on this graph with the function y=6x-1 has a smaller rate of change.
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
The function given on the graph is y = 5x - 6 and it is being comapred to the function y = 6x - 1.
Slope intercept form of a line is 5 ...(i)
We have,y = 6x - 1. ...(ii)
On comparing (i) and (ii), we get;
m= 6 , b = -1
The Slope of function is 6 and y-intercept is -1.
Since,5x < 6x , the function shown on the graph has smaller rate of change and a lower starting point.
The statement correctly compares the function shown on this graph with the function y=6x-1 has a smaller rate of change.

z = 50
Step-by-step explanation:
There are 4 numbers in total (5,10,15,z)
The mean is when you get the total of all the numbers and divide by how many there are
If you do the inverse then that means that 20 x 4 = total of all 4 numbers
80 = 15 + 10 + 5 + z
80 = 30 + z
z = 80 - 30
z = 50
