Airida [17]

Answer:

The equation of this line is y - 3 = 4/7(x - 7)

Step-by-step explanation:

To find this, start with the base form of point-slope form.

y - y1 = m(x - x1)

Now put the slope in for m and the two coordinates in for (x1, y1).

y - 3 = 4/7(x - 7)

Molodets [167]

Answer:

28.25 million

Step-by-step explanation:

Population of the country:

in 2001 - x million
in 2006 - 30.4 million

Population of the country as percent:

in 2001 - 100%
in 2006 - 100% + 7.6% = 107.6%

Write a proportion:

$\dfrac{x}{30.4}=\dfrac{100}{107.6}$

Cross multiply:

$107.6\cdot x=30.4\cdot 100$

Divide by 107.6:

$x=\dfrac{30.4\cdot 100}{107.6}=\dfrac{3,040}{107.6}\approx 28.25$
