A and B are both positive integers. Which expression is equivalent to - A-(-B)?
B-A
-A-B
A-B
A+B
Help
Answer: B-A
Step-by-step explanation:
We know that it is -A - (-B)
The negative sign on the A stays as it is, eliminating choices A-B and A+B.
For the sign in front of B, a double negative creates a positive. - (-B) is essentially -1 x -B, which is B. You can check this through your calculator.
Therefore, the answer is -A+B, or B-A. Hope it helps!

This graph is from a publication of the Centers for Disease Control and Prevention (2017). The y-axis shows the percentage living with diabetes.
The Board of Directors of a medical school wants to use the trend to predict the percentage in 2020 so that they can help train enough doctors to handle the growing numbers. Use a visual estimate of the line of best fit to make a prediction. Do you think your estimated line of best fit will be accurate? Explain why or why not.
Answer:
My estimate is around 16 million cases by 2020
Step-by-step explanation:
I used the formula of rise over run
(The "Rise over Run" formula is y2-y1/x2-x1)
I used 2010's total of cases 22 million and 1960's 4 million
Now I subtract 2010 and 1960
Which is 40 or 4 in this case
Then I subtracted 22 million by 4 million which is 5.5
Round 5.5 to 6 (Since it is an estimate)
Divide 6 and 4
6/4= 1.5 which I rounded to 2 million now I start at 1960's 4 million case and add 2 million for 10 year or multiply 6 by 2 which is 12 and add it by 4 which is 16
Hence 16 million

A person places $6520 in an investment account earning an annual rate of 2.5%,
compounded continuously. Using the formula V = Pert, where V is the value of the
account in t years, P is the principal initially invested, e is the base of a nfitural
logarithm, and r is the rate of interest, determine the amount of money, to the nearest
cent, in the account after 3 years.
Given:
Principal value = $6520
Annual rate of interest = 2.5% compounded continuously.
Time = 3 years
To find:
The amount of money after three years.
Solution:
Formula for the value of the amount is:
[tex]V=Pe^{rt}[/tex]
Where V is the value of the account in t years, P is the principal initially invested, e is the base of a natural logarithm, and r is the rate of interest.
Putting [tex]P=6520,r=0.025,t=3[/tex], we get
[tex]V=6520e^{(0.025)(3)}[/tex]
[tex]V=6520e^{0.075}[/tex]
[tex]V=7027.80466[/tex]
[tex]V\approx 7027.80[/tex]
Therefore, the amount of money after three years is about $7027.80.

X + 3y = -14
4x - 3y = 2
Help me
x = −12/5 and y = −58/15
Step-by-step explanation:
x+3y=−14
4x−3y=2
Add these equations to eliminate y:
5x = −12
Then solve 5x = −12 for x:
5x = −12
5x/5 = −12/5 (Divide both sides by 5)
x = −12/5
Now that we've found x let's plug it back in to solve for y.
Write down an original equation:
x + 3y = −14
Substitute −12/5 for x in x + 3y = −14:
−12/5 + 3y = −14
3y + −12/5 = −14
(Simplify both sides of the equation)
3y + −12/5 + 12/5 = −14 + 12/5
(Add 12/5 to both sides)
3y = −58/5
3y/3 = −58/5/3
(Divide both sides by 3)
y = −58/15

if g(x)=11x+3 find g(x+7) and g(x)+g(7).
Answer:
g(x + 7) = 11x + 80
g(x) + g(7) = 11x + 83
Step-by-step explanation:
g(x + 7) = 11(x + 7) + 3 = 11x + 77 + 3 = 11x + 80
g(x) + g(7) = 11x + 3 + 11(7) + 3 = 11x + 3 + 77 + 3 = 11x + 83

I don’t know what to do
Answer:
x = 14.4
Step-by-step explanation:
Similar means that the figures are proportional to each other. Because of this, we can form a problem. [tex]\frac{9}{5}[/tex] (the short side lengths) = [tex]\frac{x}{8}[/tex] (the long side lengths). Now we can solve this by cross-multiplying. If we multiply 9 · 8 we get 72, and 5 · x is 5x. 72 = 5x. Now divide both sides by 5. 72 ÷ 5 = 14.4. Therefore, x should be equal to 14.4. Does this make sense?

In 1990, the rate of change of the world population was approximately 0.09125 billion per year (or approximately 1 million people every four days). The world population was estimated to be 5.3 billion in 1990. Use the linear model to predict the world population in 2025. a. According to the model, in 2025 the world population will be 84,937,500,000 b. According to the model, in 2025 the world population will be 8,493,750,000 c. According to the model, in 2025 the world population will be 5,302,607,000 d. According to the model, in 2025 the world population will be 8,037,500,000
Answer:
According to the model, in 2025 the world population will be 8,493,750,000
Step-by-step explanation:
Rate at which population was growing per year = 0.09125 billion
Initial population figure in 1990 = 5.3 billion
World population prediction in 2010 ;
Predicted population figure :
Initial population + (population growth value per year * number of years)
number of years = (2025 - 1990) = 35 years
Predicted population figure in 2025 :
5.3 + (0.09125 * 35)
5.3 + 3.19375
= 8.49375 billion.
8,493,750,000 by 2025
