The correct answer would be B. 2/(x + 8)
When you are completing composite functions, you place the entire second function in for x in the first function. Since the letter f comes first in f o g. then we start with the f(x) equation.
f(x) = 2/x
Now since g comes next, we take the entire equation for g(x) and substitute it in.
f o g = 2/(x + 8)
This is answer B.
Answer:
1, 2, 4, 13, 26, 52 = 52's factors
Step-by-step explanation:
6 factors of 52
Answer:
15
Step-by-step explanation:
x + 3 = 2(x - 6)
x + 3 = 2x - 12
-1x = -15
=15
Answer:
(x, y) = (1, 1/3)
Step-by-step explanation:
The x-coefficient in the first equation is -2 times that in the second equation, so adding twice the second equation to the first will eliminate x:
(4x -9y) +2(-2x +3y) = (1) +2(-1)
-3y = -1 . . . . simplify
y = 1/3 . . . . . divide by -3
The y-coefficient in the first equation is -3 times the y-coefficient in the second equation, so adding 3 times the second equation to the first will eliminate y:
(4x -9y) +3(-2x +3y) = (1) +3(-1)
-2x = -2 . . . . . . simplify
x = 1 . . . . . . . . . divide by -3
The solution is (x, y) = (1, 1/3).
Answer:
Step-by-step explanation:
3(10 – 4x) + 6 = 12
first you need to use the distributive property
30 – 12x + 6 = 12
then subtract 6 from each side
30 – 12x = 6
then subtract 30 from each side
– 12x = -24
divide both sides by negative 12
x = 2
