Answer:
0.1111... and 11.11...%
The decimal number is obtained through the division of 1 by 9. To obtain the percentage, multiply the result of this division by 100.
Answer:
1734.1591
Step-by-step explanation:
Answer:
which appears to be from the list x=ln9-5/3
Step-by-step explanation:
We take the natural logarithm of both sides as the inverse operation to an exponent on e. This allows us to use log rules to rearrange the problem.
We know that as inverse operations, ln e =1.
Answer:
-
Step-by-step explanation:
This is not solvable, because there is only one equation without an inequality or equal sign.
Answer: (f+g)(5)=37
Step-by-step explanation:
(f+g) (5) is the same as saying f(5)+g(5). Since we are given f(x) and g(x), we can use them to solve. There are two ways to solve. One is to find f(5) and g(5), and then add them together. Another way is to do (f+g)(x), then plug in x=5. I will show both methods.
Method 1
f(5)=4(5)-7 [multiply]
f(5)=20-7 [subtract]
f(5)=13
g(5)=3(5)+9 [multiply]
g(5)=15+9 [add]
g(5)=24
(f+g)(5)=13+24 [add f(5) and g(5)]
(f+g)(5)=37
--------------------------------------------------------------------------------------------------------
Method 2
(f+g)(x)=4x-7+3x+9 [combine like terms]
(f+g)(x)=7x+2
(f+g)(5)=7(5)+2 [plug in x=5]
(f+g)(5)=35+2 [add]
(f+g)(5)=37
--------------------------------------------------------------------------------------------------------
Now, we know that (f+g)(5)=37. We confirmed this with both methods.
