Answer:

Step-by-step explanation:
Point slope form:

<em>Note: </em>
- <em>m represents the slope</em>
- <em>(x1,y1) represents the coordinate point</em>
Our answer would be 
I just took the quiz, the answer is A: Critical values=0.312; there is sufficient evidence to support a claim of a linear correlation between before-and-after weights.
To answer this question, we have the start-up costs of $ 52,000
A monthly inflation of $ 0 is assumed
Operating costs are $680
The daily gain is $960
For the Part A.
The inequality that this situation represents

So:

Where d represents the number of days.
For the Part B.
To start earning, you must replace all the initial investment and cover the expenses per day. The time that must pass for this to happen is obtained by clearing "d" from the inequality.

d> 185.71 days
Then, the sum of the net profits will be greater than the initial investment after 186 days of starting the business.
we have given an expression
.
we have given the value of x,y and m .
.
we need to find the value of expression mx-y.
we need to plug the respective values and solve.
.
7 is the value of expression mx-y.
