Answer: second option
Step-by-step explanation:
To find the inverse function of the given function f(x):
You need to:
Substitute 
into the function:
Now, you need to solve for "x", to do this, you must divide both sides of the function by 2:
Now, replace "x" with "y" and replace "y" with "x":
Therefore, substituting 
you get:
or 
3 1/16=49/16. I hope this helped. :) Brainlest answer ? :)
It took them 4 days until they arrived at their destination.
314 × 4 = 1256
Another way of solving it:
Total amount of miles ÷ miles per day = The amount of days.
1256 ÷ 314 = 4
Answer:
a = 30
2a = 60
3a = 90
Step-by-step explanation:
3a + 2a + a = 180 ( Sum of angles of a triangle is 180)
6a = 180
a = 180/6
a = 30
2a = 2 x 30 =60
3a = 3 x 30 = 90
An algebraic expression consists of one or more numbers and variables, for 1/8y it will be y+1/8
