Answer:
I think it should be the third option
Answer:
8-2/3-1
Step-by-step explanation:
slope equation is y2-y1 over x2-x1 so in that case you would put on top the 8-2 and then for the bottom you would put the 3-1
Basically, all you have to do is substitue the terms given at the top.
x = -3
y = 6
z = -4
<em>The first one will be set up like this:</em>
(-3) + 6 + (-1) = 2
<em>The second one will be set up like this: </em>
-15 + (- -3) + 6 = -6
<em>The third one will be set up like this:</em>
3(-3) - 2(6) + (-4) = -25
<em>The fourth one will be set up like this:</em>
2(-4) - 3 (6) + 4(-3) = -38
<em>The fifth one will be set up like this: </em>
3 ( -3) + 2 (6) + (-4) = -1
<em>The sixth will be set up like this: </em>
(-3)(-4)
---------- = -1
-2 (6)
<em>The seventh will be set up like this:</em>
2 (6) (-4) - 3 (-3) = -39
Hope this helps! Have a good day/night! c:
The equation would be 35=5x. ‘x’ is the number of seashells her brother has, and the 5 in front of the x is showing that she has 5 times more than him. to find how many her brother has, divide both sides of the equation by 5 to make the x stand alone. you should then get 7=x, meaning that her brother has 7 shells
Answer:
a) 
b) 6.84 million
c) 2028.52
d) 47 years
Step-by-step explanation:
a)Here we know standard exponential growth rate is

In this put t=0 and a(t)=6.27 million
thus we get a = 6.27 million
now 
this is equal to(in 2012)=
b)Put t = 6
we get

=6.84 million
c) 
take log both sides
we get 16.52 years
d) 
take log both sides we get 47 years to get double the current population.
