They would most likely win because they already won 12/20 so that is the strongest outcome
Answer:
if you bought 60 feet of copper pipe at $1.25 per foot, the total price would be $75

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
.
