Answer: The answer to the first question is C(20%)
Step-by-step explanation: 1. you need to find the absolute decrease which is subtracting 350-280= 70.
2. now you need to find the percent decrease which is dividing the absolute decrease by the whole price.. so.. 70/350= .20
3. now just multiply .20 *100 = 20%
Distribute on the left
217+111x-185=-4
Combine like terms
111x+32=-4
Sybtract 32 from both sides
111x=-36
Divide both sides by 111
x= -36/111
x=-12/37
Final answer: x=-12/37

Answer:
161
Step-by-step explanation:
Given the functions
f (x) = 2x^2 – 1
g(x) = 3x
we are to find f(g(3))
First look for the composite function f(g(x))
f(g(x)) = f(3x)
f(3x) = 2(3x)² - 1
f(3x) = 2*9x² - 1
f(3x) = 18x² - 1
f(g(x)) = 18x² - 1
Substitute x = 3 into the result
f(g(3)) = 18(3)² - 1
f(g(3)) = 18*9- 1
f(g(3)) = 162-1
f(g(3)) = 161
Hence f(g(3)) is 161
