Answer:
B
Step-by-step explanation:
1) Look at the y-intercepts.
The y-intercepts on both equations are the same: 5. That means both equations touch the y-axis at (0,5).
That means we can rule out both A & C.
2) Calculate the rate of change (a.k.a. slope) of f(x).
To do this, we must use two points to find the change of y over the change of x. From the graph, we can use the points (1,2) and (2,-1).
Δy / Δx = 
<em>*The little triangles are the Greek symbol delta. They mean change in...*</em>
That means that the slope of f(x) is -3.
3) Figure out the rate of change (a.k.a. slope) of g(x).
To do this, all we have to do is look at the equation. It is written in y = mx + b format where m = slope and b = y-intercept. That means the slope is 5 as in place of "m" there is a 5.
4) The Answer
The answer is B because 5 [the rate of change for g(x)] is greater than -3 [the rate of change for f(x)].
Answer:
A. 784
Step-by-step explanation:
915 - 75 = 840 840 - 36 = 804 804 - 20 = 784
So to do that, find the point of S then transform
in (x,y) form
we see that the point 'S' is 1 unit to the right and 2 units up therefor
the point is (1,2)
so we jsut apply the thingy translation to is
x=1
y=2
x+2=1+2=3
y-1=2-1=1
the new point is (3,1)
The value of k is 3
Solution:
Let us first find the equation of the line f(x).
The points on the line are (-6, -2) and (0, 4).
Here, 
Formula to find equation of a line:
Do cross multiplication.
y + 2 = x + 6
y = x + 4
f(x) = x + 4
Given that g(x) = f(kx)
g(x) = kx + 4
The point in the graph of g(x) is ( -2, -2).
g(-2) = k(-2) + 4
we know that g(-2) = -2.
-2 = -2k + 4
Subtract 4 from both sides.
-6 = -2k
Divide by -2 on both sides.
3 = k
k = 3
The value of k is 3.
So what we need to do is divide the number of people under 16 by the number of the entire population:
first, let's get rid of the 0s:
now, we can divide:
this is 0.6507....
in order to make this into a percentage, we multiply by 100%:
0.6507*100%=65.07%
the answer is: 65 % (quite a lot!!!)
