3)
f(x) =(x+1)/4
so
f(6a) = (6a+1) / 4
f(6a) =3/2(a) + 1/4
8)
f(x) =(x+1)/4 = 0
x + 1 =0
x = -1
answer
x = -1 makes f(x) = 0
9)
(x+1)/4 >= 10
x + 1 >= 40
x >= 39
Answer
Domain is any number greater or equal 39 (x >= 39)
Well I'm still trying to solve the first question so I'll tell you the other answers
the answer for the second question is :

and for the third question :
-15=-15
Since both sides equal, they are infinitely many solutions
D) infinitely many solutions
Answer:
384 inches squared
Step-by-step explanation:
The surface area for one of the sides is 8 x 8 = 64
There are 6 sides so 64 x 6 = 384
Answer:
33 = x + (3x + 1)
x = bath bombs
So 3x is three times as many bath bombs, then the plus one makes it so that the soaps sold is more than three times the amount of bath bombs sold
