Answer:

the answer is 2.4 million

Step-by-step explanation:

In order to find the rate of change, you first must find the amount that the population grew in the time period:

314-302 = 12

Now you need to calculate the number of years:

2012-2007 = 5

Lastly, divide the amount of change by the number of years:

12/5 = 2.4

The population grew by 2.4 million people per year. Hope this helps! :)

If v varies directly as w and v = 8 when w=1/2 find the equation that relate v and w
garri49 [273]

Answer:

v=kw. 8=k1/2

Step-by-step explanation:

Okay, so here's the equation. v=kw. Varies directly means if v rises, then w rises. If v decreases, then w will decrease. Let me know if that helps! (In case you need it, k=16.)

What is the equation of the line that passes through (2, -7) and (-1, 2)?
SVETLANKA909090 [29]

Answer:

y = -3x - 1

Step-by-step explanation:

The slope intercept form of the equation of a line is:

y = mx + b

where m is the slope, and b is the y-intercept.

First, we find the slope of the line using the two given points.

m = slope = (y2 - y1)/(x2 - x1) = (2 - (-7))/(-1 - 2) = (2 + 7)/(-3) = 9/(-3) = -3

Now we plug in the slope we found into the equation above.

y = -3x + b

We need to find the value of b, the y-intercept. We use the coordinates of one of the given points for x and y, and we solve for b. Let's use point (2, -7), so x = 2, and y = -7.

y = -3x + b

-7 = -3(2) + b

-7 = -6 + b

Add 6 to both sides.

-1 = b

Now we plug in -1 for b.

y = -3x - 1
