-5x - 3(-x+3x) - 5
1.) -3(-x+3x) = 3 - 9x
2.) -5 + 3x - 9x - 5
3.) 3x - 9x = -6x
4.) -5x - 6x -5
5.) -5x - 6x = -11x
6.) -11x - 5
answer is : -11x-5
Answer:
=3
Step-by-step explanation:
Combine like terms 3-6x=-15
Subtract 3 from both sides of the equation -6x=-18
divide both sides by 6 x=3
Answer:
g(4) = 7 and f(g(4)) = 43
Step-by-step explanation:
First find g:
g(x) = 3x-5
g(x) = 3(4) - 5
g(x) = 12 - 5
g(x) = 7
Plug in:
f(g(4))
f(7)
Now, find f:
7^2 - 7 + 1
49 - 7 + 1
42 + 1
f(x) = 43
Answer:
D
Step-by-step explanation:
12^2=144
144 is divided by b which also is an odd interger, there only 2 numbers : 1 and 3
if b=3, a^2=48, then there will be no a available
if b=1 , a^2=144, then a is 12 and 12 can not be divided by 9
The answer is D
