2/5 x 60 = 24
2/5 x (4x - 1) = x+5
8x - 2 = 5x + 25
3x = 27
x = 9
The value of x is 9
2 times 2 times 2 equals 8.
8 plus 1 equals 9
9 plus 4 equals 13.
The answer is 13.
( f - g )(x) = 10x - 17 and ( f ° g)(-6) = 60. The answers are option D and B
<h3>
There are different type of Function</h3>
Different types of function demands different ways of solving them. Different types are simple function, function by substitution and function of function.
Given that
f(x) =
+ 9x - 14 and g(x) =
- x + 3
( f - g )(x) will be the difference between f(x) and g(x)
( f - g )(x) =
+ 9x - 14 - (
- x + 3)
( f - g )(x) =
+ 9x - 14 -
+ x - 3
( f - g )(x) = 10x - 17
Also, if f(x) =
- 15 and g(x) = 1 - 2/3 x
( f ° g)(-6) means that we will evaluate g at -6, then evaluate f at the result of g(-6)
g(-6) = 1 - 2/3 (-6)
g(-6) = 1 + 4
g(-6) = 5
f(g(-6)) = 3(
) - 15
f(g(-6)) = 3 x 25 - 15
f(g(-6)) = 75 - 15
f(g(-6)) = 60
Therefore, ( f - g )(x) = 10x - 17 and ( f ° g)(-6) = 60
