Re write it in so that to have one single entity on the left & same on the right
log(x-1)-log5 = log[(x-1)/5]
and log(x+1)-logx = log[(x+1)/x]
So:
log[(x-1)/5] = log[(x+1)/x] ==> (x-1)/5 = (x+1)/x
Now you can solve it: x(x-1)=5(x+1)
==> x² - 6x -5 =0
Solving this quadratic equation gives x'=3+√14 & x" =3-√14
Step-by-step explanation:
Below is an attachment containing the solution.
Your answer would be 6 boxes.
Work:
We will need 3 for each, and there's 24 so we just multiply those two together: 24 x 3 = 72
If there is 12 in each box, and we need 72, we need to find out how many boxes we would need to have enough, even if there's leftovers: 72/12= 6.
So, we will need 6 boxes, and there will be none left over.
Hope I heled!
Answer:
C
Step-by-step explanation:
f(x) = ∛(x-1) has a positive slope everywhere. Graphs A, C, D all have f(x) properly shown.
g(x) = f(-x), so is a reflection of f(x) across the y-axis. Only graph C shows this properly.

Answer:
343π/6 cm³ ≈ 179.6 cm³
Step-by-step explanation:
The formula for the volume of a sphere is one of the volume formulas worth memorizing. It is ...
V = (4/3)πr³
For r = 3.5 cm, the volume is ...
V = (4/3)π(3.5 cm)³ = 343π/6 cm³ ≈ 179.6 cm³
The volume of air in the balloon is about 179.6 cm³.
