Identify the asymptotes of y=1 over x -6 A. B. C. D.
1 answer:
Answer:
D. x = 0; y = -6
Step-by-step explanation:
There is a vertical asymptote at the value of x that makes the denominator zero. That value is x=0. This is sufficient to choose the correct answer.
When x gets large, the term 1/x nears zero, so the value of y nears -6. This is the horizontal asymptote.
vertical asymptote: x = 0; horizontal asymptote: y = -6

Answer:
In 17th year, his income was $30,700.
Step-by-step explanation:
It is given that the income has been increasing each year by the same dollar amount. It means it is linear function.
Income in first year = $17,900
Income in 4th year = $20,300
Let y be the income at x year.
It means the line passes through the point (1,17900) and (4,20300).
If a line passes through two points and
, then the equation of line is
The equation of line is
Add 17900 on both sides.
The income equation is y=800x+17100.
Substitute y=30,700 in the above equation.
Subtract 17100 from both sides.
Divide both sides by 800.
Therefore, in 17th year his income was $30,700.
