Your Task: Modeling Population Growth
Human population numbers are in constant flux.
Suppose a country has a population of 20 million
people at the start of one year and during the year
there are 600,000 births, 350,000 deaths, 100,000
immigrants, and 5,000 emigrants. You and your
classmates will determine the total population
at the end of the year and then model expected
change over a longer period.

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units

step-by-step explanation:

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form

3

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3

he answer is x=1x3 because x=1 to x=3
