Subtracting a number is the same as adding its additive inverse. For which elevation do we need to find the additive inverse? What is the additive inverse of that elevation?
Yes subtracting a number is the same as adding its inverse. We have to find the additive inverse of a function.
What is additive inverse?The additive inverse of a number is the number which when we add to the number results zero.
How to find additive inverse?Complex numbers are made up of both real and fictitious numbers. A + iB, where A is the real number and B is the imaginary number, is a complex number.
The additive inverse of A + iB should now be a value that, when added to a given complex number, produces the result zero. It will therefore be -(A + iB).
Suppose we have to find additive inverse of 5.
Let the additive inverse of 5 be x.
So,5+x=0
x=-5
So the additive inverse of 5 is -5.
Hence to find additive inverse of a positive number we have to just put a negative mark and for a negative number we have put positive mark in front of the number.

Answer:
[tex]\textsf{A)} \quad -1\dfrac{3}{20}y+4[/tex]
Step-by-step explanation:
Given expression:
[tex]\left(11-9 \dfrac{3}{5}y\right)+\left(8 \dfrac{9}{20}y-7 \right)[/tex]
Remove the parentheses:
[tex]11-9 \dfrac{3}{5}y+8 \dfrac{9}{20}y-7[/tex]
Collect like terms:
[tex]8 \dfrac{9}{20}y-9 \dfrac{3}{5}y+11-7[/tex]
Subtract the numbers 11 - 7:
[tex]8 \dfrac{9}{20}y-9 \dfrac{3}{5}y+4[/tex]
Factor out y:
[tex]\left(8 \dfrac{9}{20}-9 \dfrac{3}{5}\right)y+4[/tex]
Partition the mixed numbers into fractions and whole numbers, and then subtract them separately.
Subtract the whole numbers:
[tex]\implies 8-9=-1[/tex]
Subtract the fractions by changing both fractions into equivalent fractions so both fractions have the same denominator:
[tex]\implies \dfrac{9}{20}-\dfrac{3}{5}[/tex]
[tex]\implies \dfrac{9}{20}-\dfrac{3 \cdot 4}{5 \cdot 4}[/tex]
[tex]\implies \dfrac{9}{20}-\dfrac{12}{20}[/tex]
[tex]\implies -\dfrac{3}{20}[/tex]
Put the two answers from the whole numbers and fractions back together:
[tex]\implies -1-\dfrac{3}{20}=- \left(1+\dfrac{3}{20}\right)=-1\dfrac{3}{20}[/tex]
Therefore:
[tex]\left(8 \dfrac{9}{20}-9 \dfrac{3}{5}\right)y+4=\left(-1\dfrac{3}{20}\right)y+4=-1\dfrac{3}{20}y+4[/tex]

If I want to invest my money and turn it into $900 over the course of two and a half years at the rate of 3.5%, how much money will I need to invest?
To turn $900 into $900 over the course of two and a half years at the rate of 3.5%, we can use the following formula:
Copy code
investment = (900 * (1 + 0.035)) ^ (2.5 / 1)
In this formula, investment represents the amount of money you need to invest, 900 represents the final amount you want to end up with, 0.035 represents the interest rate of 3.5%, 2.5 represents the number of years you want to invest for, and 1 represents the number of times per year that the interest is compounded.
Plugging in the values from the problem into the formula, we get:
Copy code
investment = (900 * (1 + 0.035)) ^ (2.5 / 1)
investment = ($900 * 1.035) ^ (2.5 / 1)
investment = $931.75 ^ 2.5
investment = $1434.24
Therefore, to turn $900 into $900 over the course of two and a half years at the rate of 3.5%, you will need to invest $1434.24.

The Sugar Sweet Company will choose from two companies to transport its sugar to market. The first company charges $3204 to rent trucks plus an additional
fee of $75.25 for each ton of sugar. The second company does hot charge to rent trucks but charges $275.50 for each ton of sugar.
Answer:
the first company would be cheaper because it has a lower total cost.
Step-by-step explanation:
To determine which company is more cost-effective, you will need to compare the total costs for each company based on the amount of sugar being transported.
If the first company is used, the total cost for transporting x tons of sugar will be 3204 + 75.25x dollars.
If the second company is used, the total cost for transporting x tons of sugar will be 275.50x dollars.
To determine which company is cheaper for a given amount of sugar, you can compare these two equations by setting them equal to each other and solving for x.
For example, if you want to transport 100 tons of sugar, you can set the two equations equal to each other and solve for x:
3204 + 75.25x = 275.50x
Solving for x, we get: x = 3204 / (75.25 - 275.50) = 107.8 tons
This means that if you want to transport 100 tons of sugar, the first company would be cheaper, because it costs less than the second company for any amount of sugar greater than 107.8 tons.
If you want to transport a different amount of sugar, you can repeat this process to determine which company is cheaper.

y = mx + b is slope intercept form,
where m is the slope, and b is the y-intercept.
As we can see from the picture, the line has a negative slope of 1 (we can also just say -1). We know this is the slope because it has a rise of -1 and a run of -1. (I hope that made sense lol :/)

Step-by-step explanation:
You have a pie removed from a 375° oven to a room temperature of 70° that has cooled to 300° after 10 minutes. You want to know its temperature after 20 minutes.
Law of CoolingNewton's law of cooling tells you the rate of change of an object's temperature is proportional to the difference between the object's temperature and that of its surroundings. The differential equation describing this has an exponential function as its solution. That exponential function can be written as ...
temperature = (initial temperature difference)·(cooling factor)^(time/(cooling time)) + (final temperature)
ApplicationHere, the initial temperature difference between the pie and room temperature is ...
initial temperature difference = 375° -70° = 305°
The final temperature is the room temperature:
final temperature = 70°
The cooling factor is the multiplier applied to the temperature difference in the time period "cooling time". Here, the pie is at 300°, a temperature difference of 300° -70° = 230° after a cooling time of 10 minutes. The cooling factor is ...
cooling factor = 230/305
A:) EquationThese values let us write the equation as ...
T(t) = 305(230/305)^(t/10) +70
B:) 20 minutesThe temperature after 20 minutes is found using this equation:
T(20) = 305(230/305)^(20/10) +70 = 305(46/61)^2 +70 = 243 27/61
T(20) ≈ 243.4 . . . . degrees F

Additional comment
The cooling factor can be expressed as a value that lets the exponent be t. Often, it is written as (e^k), where ...
k = 1/10·ln(230/305) ≈ -0.0282232
Then the equation is ...
T(t) = 305·e^(-0.0282232t) +70
It could also be written as ...
T(t) = 305(0.972171^t) +70
where 0.972171 = (46/61)^(1/10).
