Answer:
QII
Step-by-step explanation:
I'm thinking that this is supposed to be a quadratic and you forgot the ^2 at the end of the (x + 3). IF this is the case, then the vertex form of a quadratic is
where the h inside the parenthesis with the x- indicates side to side movement and the k indicates up and down movement. Both translations begin at the origin, of course. The important thing to remember here is that the form "x -" is constant. So if our quadratic reflects "x - 3", then it is understood to be "x - (3)" and the movement is 3 units to the right. If the quadratic reflects "x + 3", then it is understood to be "x - (-3)" and the movement is 3 units to the left. Our quadratic, then, is shifted 3 units to the left of the origin and up 2 units, putting us in QII.
If this is what it appears to be, (x + 3) + 2, then it is x + 5 which is a line that has no vertex (which is why I'm thinking it must be a mistyped quadratic!)
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.
