Answer:
[tex]x=-9[/tex]
[tex]y=4[/tex]
Step-by-step explanation:
[tex]3x+10y=13[/tex] ← Equation 1
[tex]4(-2y+x)-9x=13\\[/tex]
By simplifying the above equation we get,
[tex]-8y+=4x-9x=13[/tex] (Simplifying the brackets)
[tex]-8y-5x=13[/tex] (By subtracting [tex]-9x[/tex] from [tex]+4x[/tex]) ← Equation 2
Multiply Equation 1 by 5 and Equation 2 by 3 and add them together.
Equation 1 multiplied by 5 will give,
[tex]15x+50y=65[/tex]
Equation 2 multiplied by 3 will give,
[tex]-24y-15x=39[/tex]
Add those together,
[tex]15x+50y-24y-15x=65+39[/tex]
[tex]26y=104[/tex] (After simplifying [tex]x[/tex] values)
Therefor [tex]y=4[/tex]
By substituting [tex]y=4[/tex] to Equation 1 we get,
[tex]3x+10*4=13[/tex][tex]3x+40=13\\3x=-27\\x=-9[/tex]
Therefor we can say,
[tex]x=-9[/tex]
[tex]y=4[/tex]
Is -27 meters deeper than -31 meters
yes that is because they are both negative but when both are absolute valued, 31 is larger than 27

which is a disadvantage of purchasing and owning a home?
The answer to your question is,
B. Homeowners pay additional property taxes
-Mabel <3
Owning a home can lead to a lack of flexibility, high maintenance costs, and financial risks associated with changes in the housing market.
Explanation:A significant disadvantage of buying and owning a home is the commitment and reduced flexibility compared to renting. When you purchase a home, it becomes a major part of your portfolio, any change in the housing market can directly affect your financial status. Not to mention, if you need to move for a career opportunity or a change in life circumstances, it can be challenging to sell the house, especially if the market conditions are unfavorable.
Furthermore, home ownership often comes with substantial maintenance costs and responsibilities. Unlike renting, where the landlord typically handles maintenance tasks, as a homeowner, these responsibilities and costs are up to you. This can include routine tasks such as gardening and cleaning, to significant unexpected costs like roof replacement or plumbing issues.
Additionally, despite the potential financial return of selling the house in the future for more than you paid for it, this is not guaranteed. The housing market can fluctuate and you may not always make a profit on the resale of your home.

Mrs.gauthier plans to take her class on 2 field trips this year there are 23 students in her class and each field trip will cost $5 per student use mental math to find the total cost for both field trips
If there is 2 field trips with 23 students and each student costs $5 dollars. So for the 1st trip it will be 23x$5
1st trip- $115
And on the second trip its the same because there is 23 students that cost 5 dollars so it will be 23x5
2nd trip- $115
To find out the total of both trips youd add 115+115/
In total, for both trips it will cost $230 dollars.

theoretical probability and experimental probability are the same true or false?
Answer:
FALSE
Step-by-step explanation:
The statement 'theoretical probability and experimental probability are the same' is generally false. Theoretical probability is what we expect to happen, while experimental probability is based on actual results from experiments. With more trials, these two probabilities tend to get closer, thanks to the Law of Large Numbers.
Explanation:The statement 'theoretical probability and experimental probability are the same' is generally false. Theoretical probability is defined as the number of desired outcomes divided by the number of possible outcomes, assuming that all outcomes are equally likely. It is what we expect to happen in an experiment.On the other hand, experimental probability is the proportion of times an outcome occurs based on actual experimental results. In other words, it is the data observed from repeated trials of an experiment. It's worth noting that with an increasing number of trials, experimental probability tends to get closer to theoretical probability, in accordance with the Law of Large Numbers.Learn more about Probability here:https://brainly.com/question/22962752

Perform the indicated operation . Round the result to the nearest tenth and then to the nearest hundredth . Separate your answers by a comma . -49.256 + 17.197
Final answer:
By adding the two numbers and rounding, we first get -32.1 for the rounding to the nearest tenth and then the same result, -32.1, when rounding to the nearest hundredth.
Explanation:
To perform the indicated operation and round the result first to the nearest tenth and then to the nearest hundredth, we begin by adding the two numbers: -49.256 + 17.197. The sum of these numbers is -32.059. To round to the nearest tenth, we look at the hundredths place, which is 5, so we round up, resulting in -32.1. Next, to round to the nearest hundredth, we consider the thousandths place, which is 9, so we again round up, but since we're already at 9 in the hundredths place, the result remains -32.1.

z+5-4z=8 plz hurry plz
first, rearrange the equation like this
5 + z -4z = 8
Then, simplify the "z"s Then, subtract 5 from both sides
-3z = 3
Then, divide both sides by -3
z = -1
To check
-1 + 5 - 4(-1) = 8
-1 + 5 + 4 = 8 -1 + 9 = 8
8 = 8

How do I factor trig functions?
I am stuck on how to factor out equations like 1+sinX-cos2x=0
I am confused on where to go from here to solve the equation. Pls help.
Use cos2x =1-2sin^2x
1+sinx- (1-2sin^2x) = 1+ sinx -1+2sin^2x
=sinx+2sin^2x=sinx(1+2sinx)
Therefore
Either sinx=0 or 1+ sin2x =0
X=npi or sin2x=-1
Sin2x=sin 3pi/2
2x= npi +(-1)^n3pi/2
x=npi/2 + (-1)^n 3pi/4

Six people can sit at each table.
How many tables are needed for 175 people?
175/ 6 = 29.1
So you would need at least 30 tables.
Hope this Helps!!
So to figure this out first setup the equation to do so take note of the amount of people and how many can sit at a table.
6 and 175
so now make the equation which will be
175/6=29.1
Round to the most is 30. So 30 tables are needed to seat 175 people.

blake thinks the solution to the equation 4=6-2x is -5 is he corect? explain
He isn't correct. Blake added 6 to both sides instead of subtracting 6 from both sides which gave him 10=-2x ---> x=-5 isn't correct. Instead, he should have subtracted 6 from both sides and then divide. the answer would turn out to be x= -2
