The solution of system of linear equation x + 2y = 5 and 3x + 5y = 14 is,.
Answer:
// Solve equation [1] for variable x
[1] x = -2y + 5
// Plug this in for variable x in equation [2]
[2] 3•(-2y+5) + 5y = 14 [2] - y = -1
// Solve equation [2] for variable y
[2] y = 1
// Now we know this:
x = -2y+5 y = 1
// Use the y value to resolve x
x = -2(1) +5 = 3
Workaround:
{x,y} = {3,1}

[tex] {h}^{ + } [/tex]
An acid is a polar substance that dissolves in water and produces hydrogen ions.
What are acids?
An acid is a chemical that, when added to water, releases hydrogen (H+) ions. A hydrogen ion is made up solely of a proton. When examining the chemical formulas of various acids, we can see that they all include at least one hydrogen (H).
Any acid that entirely ionizes in solutions is considered a strong acid. This indicates that when dissolved in a solution, it emits the most hydrogen ions or protons.
For instance: Hydrochloric acid or HCl Acids are examples of organic chemicals that belong to the carboxylic acid, sulfonic acid, and phenol groups as well as the inorganic substances known as the mineral acids, such as sulfuric, nitric, hydrochloric, and phosphoric acids.
Therefore, a polar chemical that dissolves in water to form hydrogen ions is an acid.

Give an expression for the temperature of an ideal gas in terms of pressure p, particle density per unit volume rho, and fundamental constants.
The expression for the temperature is T = P/(ρ*R)
How to find the expression for the temperature?The general expression for an ideal gas is:
PV = nRT
Where:
P is the pressureV is the volumen is the number of molesR is the constant of the ideal gasT is the temperature.If we divide both sides by the volume we get:
P = (n/V)*R*T
And n/V is the particle density, then we get:
P = ρRT
Now we isolate T, the temperature, to get:

Your take home pay is $1500 after you have 22% withheld in taxes. What is your gross pay before the taxes were withheld? round your answer to the nearest penny.
Using the values given for the take home and tax as 227% , we assumed a gross pay of x value and found the gross pay to be $1923.076
Calculation of TaxGiven Data
Take home pay = $1500
Tax = 22% of gross
Let the gross pay be x
Hence, let us find 22% of x
= 22/100*x
=0.22x
Amount of pay = 0.22x
We know that the Take home pay is = Gross - Tax
Substituting our data we have
1500 = x-0.22x
1500 = 0.78x
Divide both sides by 0.78
x = 1500/0.78
x = $1923.076

For real numbers $x,$ what is the largest possible value of \[ 5 - (x-3)^2 ?\].
The largest possible value of f(x) will be -∞.
LimitFor solving this question, you can calculate the limit of f(x) for x→∞. Since the definition of limit is: the limit of f(x), as x approaches b , equals L. See: [tex]\lim _{x\to \ b \:}f(x))=L[/tex]
Therefore:
[tex]\lim _{x\to \infty \:}\left(5-\left(x-3\right)^2\right)\\ \\ \lim _{x\to \infty \:}\left(5\right)-\lim _{x\to \infty \:}\left(\left(x-3\right)^2\right)[/tex]
Applying the Constant Law - The limit of a constant is the constant itself: [tex]\lim _{x\to \infty \:}\left(5\right)=5[/tex]
Applying the Difference Law - The limit of a difference is the difference of the limits: [tex]\lim _{x\to \infty \:}\left(\left(x-3\right)^2\right)=\infty[/tex]
Thus,
[tex]\lim _{x\to \infty \:}\left(5-\left(x-3\right)^2\right)= \lim _{x\to \infty \:}\left(5\right)-\lim _{x\to \infty \:}\left(\left(x-3\right)^2\right)= 5- \infty=- \infty[/tex]
The largest possible value of f(x) will be -∞.
The result is consistent since it is possible to note that [tex](x-3)^2[/tex]positive number. Also, see that there is a difference between 5 and [tex](x-3)^2[/tex]-∞.

Let see if you know long division 3) 461
Answer:
461 = dividend
3 = divisor
Explanation:
Step 1:
Start by setting it up with the divisor 3 on the left side and the dividend 461 on the right side like this:
3 ⟌ 4 6 1
Step 2:
The divisor (3) goes into the first digit of the dividend (4), 1 time(s). Therefore, put 1 on top:
1
3 ⟌ 4 6 1
Step 3:
Multiply the divisor by the result in the previous step (3 x 1 = 3) and write that answer below the dividend.
1
3 ⟌ 4 6 1

Step 4:
Subtract the result in the previous step from the first digit of the dividend (4 - 3 = 1) and write the answer below.
1
3 ⟌ 4 6 1
- 3
1
Step 5:
Move down the 2nd digit of the dividend (6) like this:
1
3 ⟌ 4 6 1
- 3
1 6
Step 6:
The divisor (3) goes into the bottom number (16), 5 time(s). Therefore, put 5 on top:
1 5
3 ⟌ 4 6 1
- 3
1 6
Step 7:
Multiply the divisor by the result in the previous step (3 x 5 = 15) and write that answer at the bottom:
1 5
3 ⟌ 4 6 1
- 3
1 6
1 5
Step 8:
Subtract the result in the previous step from the number written above it. (16 - 15 = 1) and write the answer at the bottom.
1 5
3 ⟌ 4 6 1
- 3
1 6
- 1 5

Step 9:
Move down the last digit of the dividend (1) like this:
1 5
3 ⟌ 4 6 1
- 3
1 6
- 1 5
1 1
Step 10:
The divisor (3) goes into the bottom number (11), 3 time(s). Therefore put 3 on top:
1 5 3
3 ⟌ 4 6 1
- 3
1 6
- 1 5
1 1
Step 11:
Multiply the divisor by the result in the previous step (3 x 3 = 9) and write the answer at the bottom:
1 5 3
3 ⟌ 4 6 1
- 3
1 6
- 1 5

Step 12:
Subtract the result in the previous step from the number written above it. (11 - 9 = 2) and write the answer at the bottom.

An 800 kg cart is coasting at a constant velocity of 15 m/s. As the car coasts, a 200 kg block is dropped into it. What would be the velocity of the cart now?.
Using conservation of momentum, we will see that the new velocity is 12 m/s.
How to use conservation of momentum?
We know that the momentum un a closed system must be conserved, in this case, our system is the cart and the block.
Initially, the cart moves with a velocity of 15 m/s, and has a mass of 800 kg, then the initial momentum is:
P = 15m/s*800kg = 12,000 kg*m/s
Then a block of 200kg is dropped on the cart, so the new mass of the cart is 1,000 kg, then the new momentum is:
P = 1,000kg*V'
Where V' is the new velocity, and by conservation of momentum, we must have that:
12,000 kg*m/s = 1,000kg*V'
( 12,000 kg*m/s)/1,000kg = V' = 12 m/s.
The new velocity of the cart is 12 m/s.
