Suppose you are studying a population with the following characteristics: Birth rate = 14 per 1,000/year Death rate = 6 per 1,00

Nutka1998 [239]

Answer:

12 per 1,000 / year would be population growth

Step-by-step explanation:

To know the population growth it is important to know what it contributes to its growth and that it decreases it.

Birth rate ==> increases growth

Death rate ==> decreases growth

Immigration rate ==> increases growth

Emigration rate ==> decreases growth

Now it only remains to add those that increase growth and subtract those that decrease, like this:

14 per 1,000 / year - 6 per 1,000 / year + 5 per 1,000 / year - 1 per 1,000 / year = 12 per 1,000 / year

12 per 1,000 / year would be population growth

Solve the system of equations.

Alenkasestr [34]

Step-by-step explanation:

Step 1: Substitute x from the second equation into the second one

$2x - 9y = 14$

$2(-6y + 7) - 9y = 14$

$(2 * -6y) + (2 * 7) - 9y = 14$

$-12y + 14 - 9y = 14$

$-21y +14 - 14 = 14 - 14$

$-21y/-21 = 0 / -21$

$y = 0$

Step 2: Substitute y into the second equation

$x = -6y + 7$

$x = -6(0) + 7$

$x = 0 + 7$

$x = 7$

Answer: $x = 7, y = 0$

How do I solve this? Please and thank you!

For the first problem, the triangle is equilateral. This means that all three sides will have the same length. So you need to find a value for x that makes all three of those statements equivalent. I believe you could find it using a system of equations... but it’s been a while so don’t quote me on that.

For the second, ce and de are equal. Set them equal to each other and solve for x. Then plug that x value back into the side lengths.

Solve the following equation. Then place the correct number in the box provided. 3(2x + 5) ≥ 2(x + 6)

nikitadnepr [17]

(Distribute the 3)
6x +15 ≥ 2(x + 6)
(Distribute the 2)
6x + 15 ≥ 2x +12
(subtract 2x from both sides)
4x + 15 ≥ 12
(subtract 15 from both sides)
4x ≥ -3
(divide by 4x on both sides)
x ≥ -0.75

Hope that helped!
