Answer:
3n+10
Step-by-step explanation:
6(n+4)-4
PEMDAS
start with parenthesizes
6 x n = 6n
6 x 4 = 24
so we have
6n+24-4
subtract the 4
6n+20
simplify by dividing by common factor
6n/2 =3n
20/2 =10
3n+10
Answer:
Step-by-step explanation:
Given
Required
Solve for x
Since B is in between both points, then:
This gives
Divide by 3
Explanation:
Since we have given that
Now, we have to prove it as
Now, start the iterations:
So, first blank will be filled with
Second blank will be filled with
Hence proved.

Answer:</h3>
- Find the composite of the functions
- x/3
- All the answers are correct
- f(x) = 2+∛(x/3)
- f(x) = (x+3)/2
<h3>
Step-by-step explanation:</h3>
1. If f(x) and g(x) are inverse functions, then f(g(x)) = g(f(x)) = x. Finding the composite of the two functions will tell you if they are inverses.
2. To find the inverse of a function, swap x and y, then solve for y.
... x = 3y
... x/3 = y . . . . . matches f(x) = x/3
3. A function will pass the vertical line test. If its inverse is also a function, that, too, will pass the vertical line test. Since the inverse of a function is that function reflected across y=x, any inverse function that passes the vertical line test corresponds to an original function that passes the horizontal line test. (A vertical line reflected across y=x is a horizontal line.)
4. See 2.
... x = 3(y -2)³
... (x/3) = (y -2)³ . . . . divide by 3
... ∛(x/3) = y -2 . . . . .take the cube root
... 2+∛(x/3) = y . . . . .add 2
... f(x) = 2+∛(x/3) . . . . is the inverse
5. See 2.
... x = 2y -3
... x+3 = 2y . . . . . add 3
... (x+3)/2 = y . . . .divide by 2
... f(x) = (x+3)/2 . . . . is the inverse
