Defined as the average of a set of numbers
4/3 = 1/x.....4 lbs potatoes to $3 = 1 lb of potatoes to $x
cross multiply
(4)(x) = (3)(1)
4x = 3
x = 3/4
x = 0.75....so 1 lb of potatoes cost 75 cents
(8,6)...this means 8 lbs of potatoes cost $6
This is Transitive Property.
Blame me if you get it wrong :\
The two angles given are vertical angles which mean they are the same.
x +40 = 60
Subtract 40 from both sides:
x = 20
Given:
The function is:
To find:
The steps of finding the inverse function .
Solution:
We have,
The steps of finding the inverse function are:
Step 1: Substitute .
Step 2: Interchange x and y.
Step 3: Taking square on both sides, we get
Step 4: Adding 21 on both sides, we get
Step 5: Divide both sides by 7.
Step 6: Substitute .
, where .
Therefore, the inverse of the given function is and the arrangement of steps is shown above.
