Answer:
no error was made
Step-by-step explanation:
5x- 1/5*(20x +5) =9
distribute
5x - 4x-1 = 9
combine like terms
x-1 =9
add 1 to each side
x-1+1 = 9+1
simplify
x = 10
? is there any more context to the question?
Answer:
C
Step-by-step explanation:
For f(x) to be odd then f(- x) = - f(x)
determine whether
9 - 4(- x)² is equivalent to - (9 - 4x²) → C
2/1 = (8x-2)/9
2=(8x-2)/9
18=8x-2
20=8x
x=8/20
x=2/5
