Answer:
f (g(x)) = 12x + 8
g(f(x)) = 12x + 48
Step-by-step explanation:
These are composition of functions.
(Unless I am reading your notation wrong) Are the functions multiplying eachother? Is the F actually a lower case f ?
Simply do some substitutions.
f (g(x)) = 2 ( 6x) + 8 = 12x + 8
g (f (x) ) = 6 (2x + 8) = 12x + 48
Well 60% of 51,000 is 30,600 i wasn’t sure what the question was tho lol
Answer:
Step-by-step explanation:
<u>Expand the expression with the help of distributive property.</u>
- 2(q + 3)
- => (2 x q) + (2 x 3)
- => 2q + 6
Hence, the expanded expression is 2q + 6.
N=4
With the equation use the distributive property to multiply 3 into (n+2). And 9 into (6-n).
Then you should have 3n+6=54-9n
You add 9n to both sides to get 12n+6=54.
After you should subtract six from both sides to get 12n=48
The last step is to divide 12 from both sides to get n=4 :)
2x^2+20x = -38
2x^2 + 20x + 38 = 0
Divide both sides by 2.
x^2 + 10x + 19 = 0
The quadratic formula works very well here.
Let a = 1, b = 10 and c = 19
x = [-b +- sqrt{b^2 - 4ac}]/(2a)
Plug those values into the formula to find two answers for x.
One is negative and the other positive.
Good luck.
