Answer:
With what?
Step-by-step explanation:
Ask the question in the comments sections and I'll try to help you if I know the answer :)
All you need to remember is that the symbol ' % ' means ' /100 ',
and your life will be easy.
Answer:
3) 4(x-3)=2x+8
4) 3(x+5)=2x+2(2x-3)
5b) 150+72x=240+54x
6) 40+5x=340-45x
7)4x-5500=15(x)
hopefully this helps! let me know if it does not sure if its completely right still working on the other problems
Step-by-step explanation:
Both are D
First one:
f(g(x)) =f(x^2+3) then you x^2+3 is the x you are going to introduce in the function f
f(x^2+3)= sqrroot(x^2+3-3)= sqrroot (x^2) =x
Second:
you need to leave x alone
y = 3x^2 +1
y-1 = 3x^2
(y-1)/3 = x^2
sqrroot ((y-1)/3) = x
sqrroot ((x-1)/3) = h^-1(x)
<u>Answer</u><u>:</u>
x = -6 or x = 2
Hope you could get an idea from here.
