The solution to the system of linear equations is (x, y) = (7, 3).
How to find the missing coordinates of the two ends of a line segmentHerein we find that the coordinates of the midpoint and part of the coordinates of the ends of the line segment are known. We must determine the values of the missing coordinates by the midpoint formula:
0.5 · (x, 7) + 0.5 · (-1, y) = (3, 5)
Which is equivalent to the system of linear equations:
0.5 · x - 0.5 = 3 (1)
3.5 + 0.5 · y = 5 (2)
The solution to the system of linear equations is (x, y) = (7, 3).

Natasha has a job putting letters in envelopes to b mailed. In 1 hour she puts 42 letters in envelopes. which equation best represents y, the total number of letters Natasha puts in envelopes in x hours if she continues at this rate?
The equation which best represents the total number of letters Natasha puts in envelopes in x hours is y = 42x.
Given,
Number of letters Natasha puts in envelopes = 42 letters in 1 hour
Total number of letters Natasha puts in envelopes in x hours = y
We have to find the equation which best represents y:
Here,
Natasha puts 42 letters in 1hour
So, in x hour Natasha can put 42 × X letters.
That is,
y = 42 × x
y = 42x
Therefore, the equation which best represents the total number of letters Natasha puts in envelopes in x hours is y = 42x.

Error Analysis henry incorrectly said the rate 1/3 / 1/6 can be written as the unit rate 1/18 pound per gallon. What is the correct unit rate? What was Henrys likely error?
The unit rate is 2 pounds per gallon.
Henry's likely error could have been that he multiplied fractions instead of dividing.
Given the rate 1/3 / 1/6 pound per gallon, this can be written in the unit rate by dividing 1/3 by 1/6 pound per gallon.
So, 1/3 divided by 1/6 can be written as [tex]\frac{1/3}{1/6}[/tex]
which further can be simplified as [tex]\frac{1}{3}[/tex] × [tex]\frac{6}{1}[/tex]
and the answer comes out to be 2
Hence, the unit rate is 2 pounds per gallon.

Carl placed $3,700 in a savings account that compounds interest annually for a rate of 2%. How much will he have in the account for 10 years?
Carl will have $4514 in his account for 10 years
How to calculate the amount of money in carl account ?Carl place $3700 in a savings account, this means that the principal is $3700
The rate is 2%
= 2/100
= 0.02
The number of years is 10
Therefore the money that will be in the account for 10 years can be calculated as follows
3700(1 + 0.02¹⁰)
= 3700(1.02¹⁰)
= 3700(1.22)
= 4514

C. C = 9/5 (F - 32)
D. C = 5/9 (F - 32)
The formula that correctly solves for C is D. C = 5/9 (F - 32)
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .
The given formula is,
F = 9/5C + 32
where Celsius is C, and degrees Fahrenheit is F
To solve for C let us isolate C to the one side and other terms to the other,
9/5 C = F - 32
Multiplying both side by 5/9 we get,
9/5 C *5/9 = 5/9* (F - 32)

the soil for house plants consists of 12 percent water.if someone wants to plants flower that need 28 percent water in the soil, how many litters of water they need to add to 5 kg of soil?
1.111 liters of water must be added to 5 kilograms of soil.
How much water we need to add in a soil sample
According to the statement, water percentage is equal to the ratio of water mass divided by the total mass of water and dust and multiplied by 100. Then, the initial and final percentages are defined below:
Initial percentage
y / 5 = 0.12 (1)
Final percentage
(y + x) / (5 + x) = 0.28 (2)
Then, we need to resolve the resulting system of linear equations:
y = 0.6 (1)
y + x = 1.4 + 0.28 · x
0.72 · x = 1.4 - y
x = 1.944 - 1.389 · y
x = 1.111
We need to add 1.111 kilograms of water. If the density of a kilogram per liter, the volume required in liters is:
V = (1.111 kg) / (1 kg / L)
V = 1.111 L
1.111 liters of water must be added to 5 kilograms of soil.

Find the interest earned on a $30,000 deposit for six months at 1% interest, compounded continuously.
The interest earned on even a $30,000 deposit compounded monthly at 1% is $15150.75.
What exactly is compound interest?Compound interest is applied when the principal amount changes after the specified time period.
For example, if you give someone $500 at a 10% yearly interest rate, $500 is your principal amount. After one year, the interest will be $50, and the principle amount will indeed be $550; therefore, the interest for the following year will be $550, not $500.
According to the given data:P = P₀e^rt where r represents the annual interest rate as well as t represents the time period in years.
So,
P₀ = 30000
r = 1% = 0.01
t = 6 months = 0.5 year
So,
P = 30000e^0.01(0.5)
P = 30000 × 1.5050250835
P = $45150.752505
So, interest
I =45150.752505- 30000 = $15150.75
The interest earned on even a $30,000 deposit over six months at 1% compounded daily is $15150.75

Given, Since January 2000,
The population of the city of Brownville has grown according to the mathematical model.
Y= 720,500(1.022) x
Where, X= number of years
To find: If this continues, predict the year during which population of Brownville will reach 1,548,800
Starting population = 720,500
Growth rate = 1.022
(720500) (1.022) x = 1,548,800
1.022x = 2.1496
Taking log on both sides
log1.022x = log2.1496
x log 1.022 = log 2.1496
x=log 1.022×2.1496
