Answer:
Two questions:
Question 1: given .
Answer 1:
Question 2: given .
Answer 2:
Step-by-step explanation:
So is used in most classes to represent the inverse function of .
The inverse when graphed is a reflection through the y=x line. The ordered pairs on implies are on .
This means we really just need to swap x and y.
Since we want to write as a function of x we will need to solve for y again.
Question 1:
Swap x and y:
We want to solve for y.
Add 3 on both sides:
Make the left hand side a fraction so we can cross-multiply:
Cross multiply:
Simplify right hand side:
Divide both sides by (x+3):
So .
Question 2:
Swap x and y:
Make left hand side a fraction so we can cross multiply:
Cross multiply:
We have to distribute here:
Add 3x on both sides:
Divide boht sides by x:
You could probably stop here but you could also simplify a little.
Separate the fraction into two terms since you have 2 terms on top bottom being dividing by x:
Simplify second fraction x/x=1:
So .
Answer:
83.3%
Step-by-step explanation:
Games won: 80% of 15 plus 3 more: 12 + 3 = 15 games won out of 15 + 3 games played.
Percentage of matches won: 15/18 = 0.833333 ... → 83.3%
