Answer:
1.19
Step-by-step explanation:
1) Shift the decimals of both 0.8449 and 0.71 to the right by 2 decimal places. (This is needed to convert 0.71 to 71, since long division must divide by a whole number.)
84.49 ÷ 71
2) Use the algorithm method.
1 . 1 9
7 1 | 8 4 . 4 9
7 1 .
1 3 . 4
7 . 1
6 . 3 9
6 . 3 9
3) Therefore, 0.8449 ÷ 0.71 = 1.19.
1.19
1.)convert into equation: 90=11x
2.)simplify and solve: x=8.18 lbs
8.18 lbs
Y=62
X=122
cuz triangles equal 180
Answer:
use symbolab, it helps explain your math problems step by step.
Step-by-step explanation:
If the functions are inverses, then f(g(x)) = x.
A.
![\displaystyle f(g(x))=f\left(\frac{3x+1}{3}\right)=\frac{1}{\frac{3x+1}{x}-3}\\\\=\frac{1}{\left(\frac{3x+1-3x}{x}\right)}=\frac{1}{\left(\frac{1}{x}\right)}=x](https://tex.z-dn.net/?f=%5Cdisplaystyle%20f%28g%28x%29%29%3Df%5Cleft%28%5Cfrac%7B3x%2B1%7D%7B3%7D%5Cright%29%3D%5Cfrac%7B1%7D%7B%5Cfrac%7B3x%2B1%7D%7Bx%7D-3%7D%5C%5C%5C%5C%3D%5Cfrac%7B1%7D%7B%5Cleft%28%5Cfrac%7B3x%2B1-3x%7D%7Bx%7D%5Cright%29%7D%3D%5Cfrac%7B1%7D%7B%5Cleft%28%5Cfrac%7B1%7D%7Bx%7D%5Cright%29%7D%3Dx)
The functions are inverses of each other.
B. The domain of f(x) = x≠3. The domain of g(x) is x≠0.
The domain of f(g(x)) is (-∞, 0) ∪ (0, ∞).
The domain of g(f(x)) is (-∞, 3) ∪ (3, ∞).
