We are given with the initial population and is asked for the final population after n years. in this case, we use the formula P(n) = Po* (1 + r)^n where r is the rate of growth. 1) P(n) = Po* (1 + r)^n P(n) = 8600* (1 + 0.03)^3 P(n) = 9397 people
2) P(n) = Po* (1 + r)^n P(n) = 1500* (1 + 0.02)^4 P(n) = 1624 deers

Which system of equations can be used to solve for the point of intersection of the lines on the graph? A) y = x - 7; y = 2x + 2

ratelena [41]

Answer:

C) y = 2x + 7; y = 2x + 2

Step-by-step explanation:

The two lines are parallel and so will have the same slope.

From the graph, the slope of both lines are two.

Using slope intercept formula, y=mx+c, with m=2, we have y=2x+c

The blue line has a y-intercept of 2 so the equation is

$y = 2x + 2$

The red line has a y-intercept of -7 so the equation is

$y = 2x - 7$

Hence the system is

y=2x+2

y=2x-7

The correct answer is C

Write an equation in point-slope form of a line that goes through the points (1,4) and (3,-10). Do not use any spaces in your an

olasank [31]

Answer:

y-4=-7(x-1) OR y-(-10)=-7(x-3)

Step-by-step explanation: The point-slope form is $y_$ - $y_{1}$ = $m_$ ( $x_$ - $x_{1}$ )

In slope-intercept form, the equation would be y = -7x + 11

You could find the slope by using the slope equation, $\frac{y_{2} -y_{1} }{x_{2} -x_{1} }$ .

Using that, you would get -7. Thus by inserting one of the points and the slope in the point-slope equation, you will get your answer.

The linear parent function, f(x) = x was transformed to create a graph g(x) = f(x) - 1

levacccp [35]

Subtracting 1 from the function notation will decrease the y-values on the graph by 1 unit.

This will shift then entire graph of f down by 1 unit to create the graph of g.

Hello, maybe you could please take 5 minutes out of your day to help me please :) id really appreciate it!

Answer:

D

Step-by-step explanation:

Alright, so we know that they can unload 25 trucks in 5 hours.

If we do 25/5 We find out that they can unload <u>5 trucks per hour</u>

Unfortunately, that is not one of the answers, so we will have to do some investigating to find something that is <u>equivalent</u>!

After evaluating the available answers, you can find that answer D lines up with our first assumption!

Every 1/5th of an hour the Fast-Pack people can unload a truck!

We can calculate this by writing:

1/5*25=<u>5</u>

<u></u>

Please let me know if you have any confusion! :)
