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

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?

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!

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

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

Hope this helps

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

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.
