Answer:
fg(x) = √143x+121
Step-by-step explanation:
in such function we go right to left
given = f(x) = √11x and g(x) = 13x + 11
fg(x) =
f( 13x + 11 )
√11( 13x + 11 )
√143x+121
therefore found fg(x) = √143x+121
4 divided by 3,678= 0.00108754758
7 divided by 4,983=0.00140477623
53.96+0.17x =57.96+0.12x
0.17x-0.12x=57.96-53.96
0.05x=4.00
x=80 mi
Answer:
Step-by-step explanation:
<u>Given:</u>
- f(x) = 7x² - 3
- g(x) =
<u>To find f(g(x)), substitute x in f(x) with the value of g(x):</u>
- f(g(x)) =
= 7(2x³) - 3 = 14x³ - 3
This represents the amount of money she earns every hour, where x is the number of hours.
Hey Kat! :)
Glad to see you on Brainly.
Look below and watch how we solve this problem.
Ask any questions if you need it! I'll respond when you need it!
This is a bit of a hard, one. So please ask questions.

Please use the rule a/b x c/d = ac/bd while solving.
After using that equation, it should look like this:
2 x -5 x -3 / 7 x -8
Simplify 2 x -5 to -10.
Now, it should look like -10 x -3 / 7 x -8
30/7 x -8
30/-56
- 30/56 (the negative is front of the WHOLE equation.)
-15/28 is our final answer.
