Answer: The inverse of the linear function f(x)=2x+1 is f^(-1) (x) = (1/2)x-1/2
Solution
f(x)=2x+1
y=f(x)
y=2x+1
Isolating x: Subtracting 1 both sides of the equation:
y-1=2x+1-1
y-1=2x
Multiplying both sides of the equation by 1/2:
(1/2)(y-1)=(1/2)2x
(1/2)y-1/2=x
x=(1/2)y-1/2
Changing "x" by "f^(-1) (x)" and "y" by "x":
f^(-1) (x) = (1/2)x-1/2
Answer:
4^-2
Step-by-step explanation:
The rules of exponents tell you ...
(a^b)(a^c) = a^(b+c)
This means ...
(4^6)(4^-8) = 4^(6-8) = 4^-2
Step-by-step explanation:
first you find 60% of 357.50 which is $214.50. Next you would add $357.50+214.50=572
so the awnser is
the sale price of a popular smart phone is $572.
Hope this helps!!
I'd still double check with someone on this but I believe that the answer is ×=(-6/5m+3/5p) I'd still double check but I'd ur in a big hurry and just need it done then put that
