You said that 'A is 30' right there in the equation
so it would be
Xsquared=30
Using linear functions, we have that:
A.
For Company A: 
For Company B: 
B. The salaries will be the same after 7 years.
A linear function is given by:
In which:
- m is the slope, which is the rate of change.
- b is the y-intercept, which is the initial value.
Item a:
- For Company A, the salary starts at $31,000, with a raise of $3,000 each year. Thus,
, and the salary after n years is given by:
- For Company B, the salary starts at $38,000, with a raise of $2,000 each year. Thus,
, and the salary after n years is given by:
Item b:
- They will be the same after n years, for which:
Then
The salaries will be the same after 7 years.
A similar problem is given at brainly.com/question/24282972
Process average or mean
is computed by dividing the total of the measurements made on the process by the number of measurements used to compute the total approximates. For example a coach wants to know if football players
who warm up before a game will score more points than those who don't warm up.
He will break the team up into two groups and make sure each player gets equal
time on the field. He will then count how many points each player makes during
the game. After counting them, add the scores of the group that he divided and
then divided it by the number of player in that group to get an average score
on teams that warm up or do not warm up before the game.
