Pick an x value like x = 2
Note that f(2) = 1 and g(2) = 2. This shows we've doubled the f(x) value to get g(x). Therefore k = 2.
Or you could pick on x = 4 to see f(4) = 2 and g(4) = 4. The output of f(x) has been doubled as well.
It doesn't matter what x is since we'll have this doubling effect go on. I recommend picking x values where the points on the blue graph land perfectly on a grid location. Something like x = 5 seems a bit tricky.
Answer:
K = 2

Error Analysis: George was trying to rearrange the formula below to slope-intercept form, y = mx + b. by
solving for y. Identify her mistake and correct the error.
y + 20 = 2(x +20)
y + 20 = -x +20
PLEASE HELP!
Answers
Answer:
George's mistake would be:
Instead of 2x + 40, she has made - x + 20.
Step-by-step explanation:
Slope - Intercept Form = y = mx + b
y + 20 = 2(x +20)
y + 20 = 2x + 40
- 20 - 20
----------------------
y = 2x + 20
(Should have been the answer)
BUT,
George's Solving:
y + 20 = 2(x + 20)
y + 20 = -x + 20
George's Mistake would be her miscalculation during her 2nd step. Where instead of distributing 2 to (x + 20), she has changed it to -x + 20, when in reality, it should have been 2x + 40.

Answer:
y = 2/3x +6 for x< -3
y = 2/3x +1 for x> 3
Step-by-step explanation:
The graph is a line for x < -3
( - 6,2) and ( -3,4)
The slope is m= ( y2-y1)/(x2-x1)
m = ( 4-2)/(-3 - -6) = 2/ ( -3+6) = 2/3
The slope is 2/3
Using point slope form
y-y1 = m(x-x1) and the point ( -6,2)
y -2 = 2/3(x - -6)
y -2 = 2/3(x +6)
y-2 = 2/3 x +4
y = 2/3x +6 x< -3
The graph is a line for x > 3
(3,3) and ( 6,5)
The slope is m= ( y2-y1)/(x2-x1)
m = ( 5-3)/(6-3) = 2/ (3) = 2/3
The slope is 2/3
Using point slope form
y-y1 = m(x-x1) and the point (6,5)
y -5 = 2/3(x - 6)
y-5 = 2/3 x -4
y = 2/3x +1 x> 3

[tex]=\dfrac{2-4\cos (2A) + 1 + \cos (4A)}{8}[/tex]
[tex]=\dfrac{1}{8}\bigg(3-4\cos (2A)+\cos (4A)\bigg)[/tex]
LHS = RHS [tex]\checkmark[/tex]
Let's start from LHS...
LHS = sin^4A = sin^2A * sin^2A
We can apply a few formulas here;
cos 2A = 1 - 2sin^2A
sin^2A = (1 - cos2A) / 2
cos2A = 2cos^2A - 1
cos^2A = (1 + cos2A) / 2
According to the second formula, sin^2A * sin^2A = (1 - cos2A) / 2 * (1 - cos2A) / 2.
(1 - cos2A) / 2 * (1 - cos2A) / 2 = 1/4(1 - cos2A)^2
We can simplify "(1 - cos2A)^2." Remember that (a - b)^2 = a^2 - 2ab + b^2. Similarly (1 - cos2A)^2 = (1 - 2cos 2A + cos^2 2A);
1/4(1 - cos2A)^2 = 1/4(1 - 2cos 2A + cos^2 2A)
According to the fourth formula, cos^2 2A = (1 + cos4A) / 2;
1/4(1 - 2cos 2A + cos^2 2A) = 1/4(1 - 2cos 2A + (1 + cos4A) / 2)
= (taking LCM) 1/4( (2 - 4cos 2A + 1 + cos4A)/2 )
= (simplified) 1/8(3 - 4cos 2A + cos 4A)

Answer:
55
Step-by-step explanation:
No matter what happens in between, the average rate of change between 2 points of any interval is the slope of the 2 points of the interval.
The 2 points are (-8, -50) and (-6, 60), and we need to find the slope (which, as a reminder, is change in x over change in y):
(60-(-50))/(-6-(-8)) = (110)/(2)=55
Therefore, the average rate of change between the interval -8≤x≤-6 is 55.
