The correct answer is C. m-1(x) = 
You can find the value of any inverse function by switching the m(x) and the x value. Then you can solve for the new m(x) value. The end result will be your new inverse function. The step-by-step process is below.
m(x) = 5x - 5 ----> Switch m(x) and x
x = 5m(x) - 5 ----> Add 5 to both sides
x + 5 = 5m(x) ----> Divide both sides by 5
= m(x) ----> Change the order for formatting purposes.
m(x) =
And this would be your inverse, which matches answer C.
Answer:
#3 1/2
Step-by-step explanation:
if you start where the line and the boxes in the graph line up like at (0,-2) and then you go up 1 and right 2 the line will be there again line up with the boxes and since slope is rise/run it is 1/2
Answer:
Area of a rectangle = 42 square units
Step-by-step explanation:
Area of a rectangle = length times width.
l = (2c + 1) when c = 3, the length = 2 · 3 + 1 ; l = 6 + 1 = 7
w = (3 + c) when c = 3, the width = 3 + 3; w = 6
Area of a rectangle = length times width
Area of a rectangle = 7 · 6
Area of a rectangle = 42 square units
Answer: (-5x2 - 8x + 7) - (5x2 - 4)
Step-by-step explanation:
= -5x2 - 8x + 7 - 5x2 + 4
= -5x2 - 5x2 - 8x + 7 + 4
= -10x2 – 8x + 11
Answer: = (-5x2 - 8x + 7) - (5x2 - 4)
Ill write A for alpha and B for beta.
AB = c/a and A + B = -b/a
A^4 + B^4 = (A^2 + B^2)^2 - 2A^2B^2
= [(A + B)^2 - 2AB] ^2 - 2A^2B^2
Plugging in the values for A+B and AB we get
A^4 + B^4 = [(-b/a)^2 - 2c/a]^2 - 2(c/a)^2
= (b^2 / a^2 - 2c / a)^2 - 2c^2/a^2
= (b^2 - 2ac)^2 - 2c^2
---------------- -----
a^4 a^2
= (b^2 - 2ac)^2 - 2a^2c^2
-----------------------------
a^4
