Answer:
g(x + 8) = 10x + 105 wherever you see it among your answers.
Step-by-step explanation:
I think I have enough here that I can answer the question, but you should always put in your givens.
f(x) = 10x + 25 Put g(x) where you see x in f(x)
f(g(x)) = 10(g(x) + 25 Put the value for g(x) where you see g(x)
f(x+8) = 10(x + 8) + 25 This might be the answer
From here it is a guess.
f(x+8) = 10x + 80 + 25 Combine the like terms
f(x+8) = 10x + 105
Are you trying to find x?
X2 - 25 = 0
Add 25 on each side.
x2 = 25
Divide by 2 on each side.
x = 12.5
Answer: x > 5
Reason:
Add 8 to both sides to undo the -8
We have x-8 > -3 become x > -3+8 which becomes x > 5
We can replace x with anything larger than 5.
To graph this on a number line, plot an open hole at 5. Then shade to the right.
